I think Burnie really put it the best way when he was talking about Gavin, and this isn't his exact quote, but something like this. "Gavin is on of the cleverest people I know, and unless it sounds completely f*#&ing stupid, then I believe him, especially if its anything remotely to do with cameras."
LewisB776 I actually saw one of the slowmo guys videos getting played in a science class in my high school when I was walking down the hallway to use the bathroom.
6:42 OMG. I'm stunned. Been a professional photographer for over 50 years. Held a photojournalist press pass for many moons. Worked for AP and UPI back in the 70's. Thought I knew my profession better than most. And yet, never realized the how f/stops were arranged. Sheesh. I feel stupid. How the hell did I miss this for so many decades? Thanks, Gavin, for teaching this old lenshound a new trick! ("Lenshound", that confirms how old I am!)
They’re the same person, but Gavin’s a camera man, he’s gotta know his stuff about cameras as he’s had multiple jobs involving them, he also has a good general knowledge but has trouble describing and putting his thoughts into words, and when he’s in environments where he’s not confident or just not performing well he turns into the Gavin we know and love at Achievement Hunter.
Gavin: "What if your legs didn't know they were legs?" Also Gavin: "If I want to reduce the motion blur in the image, I have to reduce the shutter angle but if I want any depth, I have to lower the aperture.."
I love watching Gavin talk shop. Just goes to show how much work is put into these videos. I'm looking forward to the video on navigating electricity flicker, because this is a common problem for those of us that use webcams indoors.
That's more a problem with the interaction of the standard video framerates and the frequency of the electricity supply -- fluorescent lights/CRT monitors flicker at the same speed as the AC current feeding them (50hz in the UK/60hz in the US; a TV for obvious reasons, and, well, IIRC fluorescents flicker at twice the mains freq, which happens to be the 180-degree shutter angle exposure, so they get out of sync quick), so you'll inevitably get the flicker on film/video at the standard 25/30fps. That's one of the uses for a 360-degree shutter, that way you get at least one flicker per frame. And if you're shooting interlaced video (for TV) I guess you're just boned, at best you'll get the light on in one half-frame and off in the next. Slowmo, you're just going to see the fluorescents/pulse-with-modulated LEDs slowly pulse no matter what, see slowmo clips from things like Top Gear of cars with LED headlights. That's why film/video productions use "hot lights" -- incandescent bulbs don't flicker, with the downside that back in the day with low-ISO film/sensors, it got really hot on stage, the guys in the monster suits in old movies could only shoot five minutes at a time, and one of the big advances in movie makeup was when they made a formula that wouldn't melt.
I think you actually get worse problems when you're recording at a different frame rate than the flicker, though. So, if you're recording video with an iPad or iPhone at their default 60 frames per second, and you have a light flickering at 50Hz, every frame is going to have a different light level due to the flicker being out of sync. Big Clive always had that problem when he was recording with an iPad--he'd always say that the flicker was far worse on the video than it actually appeared in real life.
d2factotum when did the iPad and iPhone get 60fps? Mine both still shoot in a terrible, awful, cringey pixelated mess of 720p30. And yes three adjectives were needed to describe how godawful the video quality is.
Gavin, have you ever thought about doing a photography masterclass or more of these sort of educational videos? I think you are really good at explaining things and would like to learn more about photography and film as well as maybe the editing process.
My photography course used his earlier vid Gav mentioned to discuss all of this, but this is so much more in depth. I had to share it with the prof I took the class with so many semesters ago, it just felt right. Gav knows his shit, and explains it at a perfect lay-level. Only one explanation needed from Gav, one go-through. It's the sign of a true professional and a proper instructor.
After seeing this video, I'm conviced more than ever that this guy is brilliant. I feel like Gavin has, and has had a very serious and complex job most of the time with filming and whatnot and when he's with AH it's the time when he can just not care, relax and be stupid, and I bet he finds it super liberating. This two facet personnality makes for great content on both sides!
"And that's important for any job, I think. You've got to be confident doing it and you've always got to be open to new techniques or adapting your style depending on what the subject is or what people need." Surprising and apt philosophical advice.
Or he would just go back to what he was doing. Which was being hired to shoot slow motion shots for various companies out there. Crazy to think he did that before becoming a major goofball like he is now for RT haha.
We just spent a week on this in my cinematography class and I still didn't really understand it, this was way easier to grasp, thank you Gavin. Please keep doing these
Love the way he teaches with no ego, learned a lot from this. My film school lecturers always talk with an ego and act like I'm an idiot for not knowing how things work (I came to learn, not be judged)
I love watching achievement hunter Gavin being confused about everything, and then come and watch slow mo Gavin and he knows what he's talking about and I love it
I'm not even that into this specific subject but Gavin's knowledge and enthusiasm is really infectious. I've learnt a lot from this video and actually want to know more, top work Gavvy Wavvy 👍🏼
I would probably pay to take a camera course taught by Gavin. His previous video that he talked about in this one is the thing that got me to understand shutter speed when I'd already taken a course in a lecture hall that just didn't click with me. Kudos, Gav; you're a brilliant teacher and I love it when you teach us about the way cameras work.
"If I swung an ax I'd probably put it in my shin, that's why Dan's always the one doing to AX-SHIN (action)". Idk if I'm the only one who made this association but it's right at like 14:00
Keep this sort of content up! The hallmark of a good educator is someone who can explain complex things in simple terms and you nailed that Gav! Of-course keeping things fun and throwing in the odd clip from other videos helped keep our attention as well. So crazy to think I've been watching your content for over 5 years now!
I always ignored the Slow Mo Guys RUclips vid suggestions, as I thought the presenters were the fake-Chad-lad type dumbos (like many other popular youtubers). Damn, was I wrong. I've been binge-watching the Slow Mo Guys for days now,. I'm just happy to see you guys going strong for so many years, this is top quality entertainment.
This video is so jam-packed with useful information. Prior to this I only knew the basics of some of the settings Gavin talks about but I think I've learned more about the actual practicality and relations between those settings from this video than I ever have in the past. Thanks for making this!
Fun fact to approx. 8:00: The same things automatically happens with your eye. If you focus on something very near to your eye your iris gets smaller too. This enables you to see things both even nearer and further away to your focus point unobscured. (called depth of field). For those interested, the medical term is called accomodation reflex.
Finally - Realtime 'Photograghy 101' lessons from someone who's passionate and also knows exactly what they're talking about technically. Fantastic teaching ability and easy learning. Well done....and please keep them coming.
Given that speed is the rate that a something travels in some specified distance, the slowest particles (as long as they move at all) have speed. I'm assuming here that you believe speed must be fast but I'm not sure. 'insert joke about velocity here'
NoLand's Man not necessarily, I remember an episode of top gear from like 10 years ago where they hit a car with lightning to test if it's safer. There are indoor facilities that can generate and control it, might not be as strong as natural but safer and easier to shoot.
NoLand's Man agreed, I've always wanted to see really high quality slow mo footage of lighting hitting a tree. Imagine seeing the sap inside boil instantaneously and explode out in millions of splinters.
It might not be that difficult. With still photography, you frame the shot, get your settings where you like them, and just take long exposures. With Slow Mo, I think it would be about the same, with the main challenges being lightning occurring where your shot is composed and DURING the capture, which sounds like it's probably a bit shorter than my usual shutter speed for lightning. I would be interested to see what Gav and Dan could do with it.
maybe they could travel to whatever that place was in venezuela where there is lightning everywhere at any time? it'd be easier to shoot because you can just point anywhere and wait for one (or i heard when the storm is extreme the lightning bolts are so dense you basically see a net of bolts everywhere you look, so they don't even need to wait) and you can get a cooler shot than doing it in an average storm
RankUpGaming He told the story years ago on the RoosterTeeth podcast. He basically started helping a guy who lived in his town that shot slow mo. Not much of a story, he basically just worked along side him and learned as he did.
The stuff he talks about here is like your basic 101 into photography. Go read any beginner's or starter photography book or column or blog post or anything, and you'll learn the same exact things.
He plays Halo with Burnie Burns on the Letsplay channel and he talks about his life getting involved in Rooster teeth including his time in the film industry I think its called Game Time. One of my fav videos to go back too.
As soon as you started talking about Dan, I was smiling so much, just hearing the clear admiration you have for him is so nice. This video helped me to see how different and difficult both sides of the camera are! Props to you both
This video has helped me better understand the relationships between shutter speed, and aperture more so than any other guide or book I've read to date. Much obliged Gavin!
This was incredibly helpful. I've messed with those settings on dslr cameras for videos but now I actually understand what all of them mean. Thanks Gavin!
My favorite part of this amazing video is the rare, on-camera display of respect. Gav and Dan are both highly competent, but good around a hell of a lot (definitely part of the fun of their videos). Dan is the butt of so many jokes that their relationship can come across as abusive if you watch enough videos. It's nice to see that Gavin really does hold his friend in such a high esteem. And yeah, that was an amazing lesson in photography and video-photography. I will be watching this video again many times.
Gav, you have a fantastic, accessible way of explaining topics such as this. I learned more from this one video than the photography books I've read! I'd love more, expanded videos like these, please. 👍😊
You know what's nice? When people don't say "uh" or "um" between each sentence when explaining something. It's really nice listening to Gavin explain this shit.
I watched this whole on my phone with data. That's how good it was. Also videos like this is why I can't fully enjoy Gavin on let's play, I know he is smart hahaha
This is why I respect Gavin as much as I enjoy his sense of humor - he takes the time to make a whole separate video dedicated to explaining the technical side of what he does. Fantastic.
This actually is gonna help me alot with an upcoming class photogrammetry. Cuz i didnt understand anything the teacher was saying. This clears it all up
Having watched some of Burnie's vlogs as well as this video, I was wondering how likely it is that both Gav and Burnie will be lecturers someday at University/College as they're so articulate in their fields. Anyway, this video was awesome, more like this please :D
Agreed. I don't know if Burnie has done any guest lecturing yet but he has mentioned times where he has been a guest speaker for very important presentations so at least some people can see that they/he are knowledgeable.
So I've worked with digital and film still photography and have had some formal training with cinema cameras. I still don't know why on still cameras it's called an aperture, but on video it's an iris. Anybody have an answer?
Robbie Carroll Well they are different things. Iris is the physical mechanism that has the hole in the centre, aperture is the size of the hole in the iris.
Coming from someone with no previous knowledge about cameras that don’t come stock on an iPhone, I found this to be very interesting and well explained. Really nice job, Gavin. You could totally teach a whole class about camera stuff like this.
I'm a decent amateur still photographer, been doing that for more than a decade now. I'm pretty sure this is the clearest explanation I've ever seen for exposure in still photography, and then the video-specific stuff (which was mostly new to me) made perfect sense all the way through. Brilliant video.
Gavin I just bought my first DSLR and although you didn't make this video to teach people about still photography, this is the video I've been coming back to for an explanation on aperture etc. You're an amazing teacher! I've taken a photography course in the past and it was just gobbledygook and I didn't retain any of this information. You really make things clear and easy to remember.
Everything about the physics of capturing images in barely 16 minutes... Dude, you're awesome. This video together the DSLR shooting boost anyone's interest in photography!
Hey, I was wondering if you guys ever had the idea to film a sword fight, specifically a parry. I've heard that there is a tremendous amount of bend in the swords, so I thought it would be cool to see.
Great video! About the angle though, when you're using an insanely high shutter speed, does the angle still matter that much? Wouldn't you rather double your shutter speed and go to 360 degrees to gather twice as much light? In other words, isn't 2000fps@360 exposing the sensor just as long as 1000fps@180? Except with 2000fps you get twice as many frames. With 180 degrees, I feel like you're throwing away half of the potential light.
I would agree that 360 vs 180 at the same shutter speed would result in more motion blur. However, that would not be true at different speeds. With 2000fps@360 and 1000fps@180 both equate to the shutter being open for 500 nanoseconds. So the same amount of motion blur would be present either way. Just with 2000 you get twice as many frames.
Darin Gilchrist You're forgetting the part where they have to playback all the footage at 25 FPS. So having the shutter set to 360° is going to create noticable blur no matter how fast the original footage was shot.
This was the greatest, most informative, easiest to understand description of shutter speed, shutter angle, aperture, etc I've ever heard. Thank you so much for this video!!!!!!
Actually going to show this to my A-Level photography teacher, took about two 50 minute lessons just to get over ISO, aperture and shutter speed :') You are great Gav
seen plenty of videos explaining the technical end of camera work. not a single one ever bothered to explain the shutter angle/frame rate relation like you did. props to you.
This video and the DSLR shutter speed video have literally been two of the most fascinating things I have ever watched. And they weren't even in slow motion! Love these educational insights, keep 'em coming!
Amazing video. So much useful information packed into it. It's unfortunate that it has a relatively low amount of views, it deserves at least 2 million. Any who, thank you to Gavin for taking the time to make it.
Awesome, thank you for actually both telling and show us what the degrees means in this case. I've actually wondered about that when you and Dan talked about it in other videos. Keep up the good work mates!
This is really enjoyable to watch Gavin. You have a great way of explaining the mechanics in an understandable way, and a good way to demonstrate it afterwards. I learned quite a bit.
The 130 people who voted 'thumbs down' on this video baffle me - this is quite frankly one of the most clear, well paced, informational explanations I have ever come across regarding aperture, light, shutter speed and ISO ever! Great job.
Dude, your DSLR video was amazing, and this one is just as good. Even though I was already fairly familiar with the concepts in both videos, you explained everything so clearly that I found them very informative.
WOW in 16:26 I feel like I just picked up like a semester of a digital film and video production course worth of knowledge. Mind BLOWN! Thank you for showing me and not just telling me. INVALUABLE!
I love all of your videos Gavin, but this is by far the most information I have ever gotten about cameras. I am very glad you started this second channel just for this type of info. Look forward to seeing more.
There are few things I find more interesting than listening to someone talk about something they're very passionate and knowledgeable about. This video hits that nail on the head.
It's fascinating to hear about this because I used confocal microscopy during my graduate studies and many of the principles you mentioned are more or less the same. One difference is that in confocal microscopy, when closing the pinhole, we are actually able to reject light from outside the focal plane, which for our applications where we want to see a specific layer of a cell is very useful. But what is very similar is the notion of the compromise between speed and brightness of the image. In microscopy, my professor called that the "triangle of despair." Basically, you can imagine 3 points labelled resolution, speed, and brightness in a triangle shape. For any single microscopy, you can draw a straight line linking 2 of those points, but you will inherently sacrifice the 3rd. So you can capture very high resolutions images with good brightness for a good signal to noise ratio, but if you're going to need to let the image exposure for a really long time. Which in normal photography is okay, just throw huge studio lights at the subject or use sunlight. But for our samples, the problem is that the fluorescent proteins we use will bleach under constant exposure to the lasers which we use to activate them. So it's always a compromise to get the best image possible given the circumstances. And I bet you we could speak with astronomers and they likely will talk about the same thing, even if their objectives are measured in metres rather than milimetres. One question, is the concept of numerical aperture at all relevant for "normal" photography and videography? It's a key factor in choosing microscope objectives but in normal videography, I feel like it might not be relevant.
Dude, that was one of the best explanation vids I've ever seen. It really shows how much you love and understand your craft. Even tho it was about slow motion, you just made everybody understand how filming works a whole lot better. Even for me who already knew the basics, you explained it in such a way that it enlightened me even more.
I really enjoyed this. My boyfriend is studying in the photography and film industries right now, but he's not always the best at explaining things to me, despite my want to understand. Gavin, you always do a superb job at explaining how things work in a way everyone can understand. Thanks!
One of the best YT videos i have ever seen.. definitely putting it up in my FAV videos. The explanation to everything was spot on. Really spot on. Man you fucking nailed the video! Nice job.
Gavin on Slow Mo Guys: "Speed and aperture"
Gavin on Achievement Hunter: Kills himself in Worms by jumping off the map
gavin with cameras: shutter speed represented by certain angles
gavin at rooster teeth: the headlight fluid leak onto him
He definitely exaggerates himself for the sake of comedy, but there's no denying he's a bit of an idiot savant.
A smart idiot
Blind Rhytm some would say, an idiot savant
I think Burnie really put it the best way when he was talking about Gavin, and this isn't his exact quote, but something like this.
"Gavin is on of the cleverest people I know, and unless it sounds completely f*#&ing stupid, then I believe him, especially if its anything remotely to do with cameras."
Super informative video, even if it's for researching... I knew nothing about this before and I feel like Gavin is a pretty good teacher.
very much agree was going to comment something like that myself
LewisB776 I actually saw one of the slowmo guys videos getting played in a science class in my high school when I was walking down the hallway to use the bathroom.
LewisB776 hey big boi
yep this was the best video on shutter and lens settings in general I've seen so far, so even without the slow mo part this is a great video to learn.
I know nothing about cameras and the terms but he made it totally understandable even for me! Very well explained!
Gavin is actually a really good teacher :)
novela rastro de mentira
He is, isn't he? :)
6:42 OMG. I'm stunned. Been a professional photographer for over 50 years. Held a photojournalist press pass for many moons. Worked for AP and UPI back in the 70's. Thought I knew my profession better than most. And yet, never realized the how f/stops were arranged. Sheesh. I feel stupid. How the hell did I miss this for so many decades?
Thanks, Gavin, for teaching this old lenshound a new trick! ("Lenshound", that confirms how old I am!)
whats your profile picture
Damn, you joined RUclips in 2006. Checks out you're a video veteran alright.
Never go old to learn something new, that’s one of the perks of technology and our evolution in such things, we can continuously learn 😊
I'm torn, I really like dumb ass, bird noise Gavin but professor Gavin is also really cool and has a ton of knowledge.
I think dumbass bird noise Gavin is what you get when Gavin relaxes and turns his brain off.
They’re the same person, but Gavin’s a camera man, he’s gotta know his stuff about cameras as he’s had multiple jobs involving them, he also has a good general knowledge but has trouble describing and putting his thoughts into words, and when he’s in environments where he’s not confident or just not performing well he turns into the Gavin we know and love at Achievement Hunter.
Yeah I love both
Why do kids not understand the difference between him just being chill and actively trying to be entertaining
Officially convinced SMG Gav and AH Gav are identical twins pretending to be the same person

Since iPhone 4, but it's a feature you need to have it jailbroken to do so.
I don't know if iPad can record 60fps, sorry.
Holy shit dude I just learned an entire photography course in less than 20 minutes
Jess Soderberg lol
I really wished he had gone into more depth on ISO, otherwise, I agree
Jess Soderberg No, this is actually pretty basic stuff.
Or 10 mins if you watch at 2x speed
Gavin, have you ever thought about doing a photography masterclass or more of these sort of educational videos? I think you are really good at explaining things and would like to learn more about photography and film as well as maybe the editing process.
He could easily do a High Speed Film Class but then again he just did lol.
@@burns0100yeah idk if it goes much more beyond this.
Ah! thats why my depth of field is so small! Thank you so much for this info!
Oh, I'm scrolling and Cody's here too :D
Cody'sLab Man you are everywhere.
My expectations are now high for your slow-mo Cody
Your depth of field isn't the only thing small xD jk
I hope to see some nice slow mo videos from you Cody.
Learned more in this video than my college photography course.
Lili Gamble same here
Lili Gamble probably because you paid attention here and not in class 😎

Don't forget the bottle as well
🤣
>15+ Minutes of in depth technical analysis
>Ends it with "So yeah you need a lot of light"
> You need a lot of light, and try to maintain a fixed distance from the lens if you move.
New shirt "Slow Mo - It's all about speed!"
Or "Slow Mo - Let there be light."
AndaleTheGreat kinda an oxymoron :P
Daniel Gloyne
Not really, speed = / = fast
Speed is the time it takes for something to get from point a to point b
Going slow is a speed
"And that's important for any job, I think. You've got to be confident doing it and you've always got to be open to new techniques or adapting your style depending on what the subject is or what people need."
Surprising and apt philosophical advice.
Gav needs to start a Vsause/SmarterEveryDay style channel.
I'd watch the shit out of it.
If the youtube/RT thing ever craps out, he could easily support himself by getting a job teaching photography at a community college. :D
Or he would just go back to what he was doing. Which was being hired to shoot slow motion shots for various companies out there. Crazy to think he did that before becoming a major goofball like he is now for RT haha.

Watch the video about DSLR cameras or televisions.
I love watching achievement hunter Gavin being confused about everything, and then come and watch slow mo Gavin and he knows what he's talking about and I love it
As a retired professor of still photography, I give my thumbs up and kudos to you and your clear explanation of exposure! Very nicely done, Gavin!
As an early film student, this is extremely helpful and also a better look at what Gav does!

Ever think you'll be in a position to capture lightning on a Phantom? Would love to see that raw power erupting from absolute darkness.
NoLand's Man not necessarily, I remember an episode of top gear from like 10 years ago where they hit a car with lightning to test if it's safer. There are indoor facilities that can generate and control it, might not be as strong as natural but safer and easier to shoot.

It might not be that difficult. With still photography, you frame the shot, get your settings where you like them, and just take long exposures. With Slow Mo, I think it would be about the same, with the main challenges being lightning occurring where your shot is composed and DURING the capture, which sounds like it's probably a bit shorter than my usual shutter speed for lightning. I would be interested to see what Gav and Dan could do with it.
maybe they could travel to whatever that place was in venezuela where there is lightning everywhere at any time? it'd be easier to shoot because you can just point anywhere and wait for one (or i heard when the storm is extreme the lightning bolts are so dense you basically see a net of bolts everywhere you look, so they don't even need to wait) and you can get a cooler shot than doing it in an average storm
Gavin, how did you get to know so much about high speed camera's? I know you worked in the film industry in Britain, but how did that happen?
RankUpGaming he probably studied photography or something
RankUpGaming He told the story years ago on the RoosterTeeth podcast. He basically started helping a guy who lived in his town that shot slow mo. Not much of a story, he basically just worked along side him and learned as he did.
Yea I remember that he enjoyed it so much and wanted to do more with it hence the slow mo guys
The stuff he talks about here is like your basic 101 into photography. Go read any beginner's or starter photography book or column or blog post or anything, and you'll learn the same exact things.
He plays Halo with Burnie Burns on the Letsplay channel and he talks about his life getting involved in Rooster teeth including his time in the film industry I think its called Game Time. One of my fav videos to go back too.
As soon as you started talking about Dan, I was smiling so much, just hearing the clear admiration you have for him is so nice. This video helped me to see how different and difficult both sides of the camera are! Props to you both
This video has helped me better understand the relationships between shutter speed, and aperture more so than any other guide or book I've read to date. Much obliged Gavin!
LOL best description ever..and also the most british thing I have ever read. *" Gav waffles on about Phantoms and that."*
This was incredibly helpful. I've messed with those settings on dslr cameras for videos but now I actually understand what all of them mean. Thanks Gavin!
I now understand the aperture science logo. Thanks Gavin!
My favorite part of this amazing video is the rare, on-camera display of respect. Gav and Dan are both highly competent, but good around a hell of a lot (definitely part of the fun of their videos). Dan is the butt of so many jokes that their relationship can come across as abusive if you watch enough videos. It's nice to see that Gavin really does hold his friend in such a high esteem.
And yeah, that was an amazing lesson in photography and video-photography. I will be watching this video again many times.
Gav, you have a fantastic, accessible way of explaining topics such as this. I learned more from this one video than the photography books I've read! I'd love more, expanded videos like these, please. 👍😊
Would be interesting to see a phantom/tiltshift lens combo. That way you may be able to shift the focus from front to back
this was super interesting
You know what's nice? When people don't say "uh" or "um" between each sentence when explaining something. It's really nice listening to Gavin explain this shit.
I've NEVER seen the basics of photography explained this well before. Fantastic job!
This is like the most informative introduction to photography/film I've ever seen
I watched this whole on my phone with data.
That's how good it was.
Also videos like this is why I can't fully enjoy Gavin on let's play, I know he is smart hahaha
its not even that he pretends to be dumb, he just goofs off and goes all relaxed...
This was absolutely fantastic.
"B, you nailed it" omg when are you guys just gonna get together
This is why I respect Gavin as much as I enjoy his sense of humor - he takes the time to make a whole separate video dedicated to explaining the technical side of what he does. Fantastic.
This actually is gonna help me alot with an upcoming class photogrammetry. Cuz i didnt understand anything the teacher was saying. This clears it all up
Having watched some of Burnie's vlogs as well as this video, I was wondering how likely it is that both Gav and Burnie will be lecturers someday at University/College as they're so articulate in their fields. Anyway, this video was awesome, more like this please :D
Agreed. I don't know if Burnie has done any guest lecturing yet but he has mentioned times where he has been a guest speaker for very important presentations so at least some people can see that they/he are knowledgeable.
I have a feeling that he's lectured at UT?? As you say though, he's been a speaker multiple times so I'm not sure.
So I've worked with digital and film still photography and have had some formal training with cinema cameras. I still don't know why on still cameras it's called an aperture, but on video it's an iris. Anybody have an answer?
Photographers are pretentious and like to use big, complicated words! 😜
Robbie Carroll Well they are different things. Iris is the physical mechanism that has the hole in the centre, aperture is the size of the hole in the iris.
I like how you didn't know the answer so you just decided to insult every photographer.
Ah, that makes sense, thanks!
V1bration You are an idiot
Once your finished with youtube, you should be a lecturer about high speed photography, and entertainment. Please like cud I want Gavin to see this.
Coming from someone with no previous knowledge about cameras that don’t come stock on an iPhone, I found this to be very interesting and well explained. Really nice job, Gavin. You could totally teach a whole class about camera stuff like this.
I'm a decent amateur still photographer, been doing that for more than a decade now. I'm pretty sure this is the clearest explanation I've ever seen for exposure in still photography, and then the video-specific stuff (which was mostly new to me) made perfect sense all the way through. Brilliant video.
You should definitely make this a series and explain the other difficulties and techniques!
Gavin Free's school for children who can't film good and want to do other stuff good too.
*HAND RAISED... Is this gonna be on the quiz?
Gavin I just bought my first DSLR and although you didn't make this video to teach people about still photography, this is the video I've been coming back to for an explanation on aperture etc. You're an amazing teacher! I've taken a photography course in the past and it was just gobbledygook and I didn't retain any of this information. You really make things clear and easy to remember.
Everything about the physics of capturing images in barely 16 minutes... Dude, you're awesome. This video together the DSLR shooting boost anyone's interest in photography!
Hey, I was wondering if you guys ever had the idea to film a sword fight, specifically a parry. I've heard that there is a tremendous amount of bend in the swords, so I thought it would be cool to see.
"It's all about speed."
Gotta go fast... to go slow. :U
Great video! About the angle though, when you're using an insanely high shutter speed, does the angle still matter that much? Wouldn't you rather double your shutter speed and go to 360 degrees to gather twice as much light? In other words, isn't 2000fps@360 exposing the sensor just as long as 1000fps@180? Except with 2000fps you get twice as many frames. With 180 degrees, I feel like you're throwing away half of the potential light.
I think he said he doesn't like the motion blur he gets at 360. I'd have to re-watch to be sure that's what he said.
I would agree that 360 vs 180 at the same shutter speed would result in more motion blur. However, that would not be true at different speeds. With 2000fps@360 and 1000fps@180 both equate to the shutter being open for 500 nanoseconds. So the same amount of motion blur would be present either way. Just with 2000 you get twice as many frames.
Darin Gilchrist You're forgetting the part where they have to playback all the footage at 25 FPS. So having the shutter set to 360° is going to create noticable blur no matter how fast the original footage was shot.
Motion blur is a result of a ratio with the shutter angle as denominator. The shutter speed is irrelevant in the motion blur achieved
Darin Gilchrist I have the same question!
Best video I've seen so far that simply explains the basics in still photography and how it relates to film. You're awesome Gavin.
This was the greatest, most informative, easiest to understand description of shutter speed, shutter angle, aperture, etc I've ever heard. Thank you so much for this video!!!!!!
Gavin...my brain hurts
I would've never thought 5 years ago that all the questions I have about a camera would be answered by fucking Gavino headlight fluid Free
Neato
Actually going to show this to my A-Level photography teacher, took about two 50 minute lessons just to get over ISO, aperture and shutter speed :') You are great Gav
I'm uncomfortable. This isn't Gavin.
Josie Anne Trust me its the same Gavin😂
Gavin looks homeless
seen plenty of videos explaining the technical end of camera work. not a single one ever bothered to explain the shutter angle/frame rate relation like you did. props to you.
This video and the DSLR shutter speed video have literally been two of the most fascinating things I have ever watched. And they weren't even in slow motion! Love these educational insights, keep 'em coming!
Amazing video. So much useful information packed into it. It's unfortunate that it has a relatively low amount of views, it deserves at least 2 million. Any who, thank you to Gavin for taking the time to make it.
Awesome, thank you for actually both telling and show us what the degrees means in this case. I've actually wondered about that when you and Dan talked about it in other videos. Keep up the good work mates!
This is really enjoyable to watch Gavin. You have a great way of explaining the mechanics in an understandable way, and a good way to demonstrate it afterwards. I learned quite a bit.
The 130 people who voted 'thumbs down' on this video baffle me - this is quite frankly one of the most clear, well paced, informational explanations I have ever come across regarding aperture, light, shutter speed and ISO ever! Great job.
And now I finally know how a camera works. Thanks, Gav and Dan, this was most lucid.
Dude, your DSLR video was amazing, and this one is just as good. Even though I was already fairly familiar with the concepts in both videos, you explained everything so clearly that I found them very informative.
WOW in 16:26 I feel like I just picked up like a semester of a digital film and video production course worth of knowledge. Mind BLOWN! Thank you for showing me and not just telling me. INVALUABLE!
I love all of your videos Gavin, but this is by far the most information I have ever gotten about cameras. I am very glad you started this second channel just for this type of info. Look forward to seeing more.
More videos like this please!! I love the tech and behind the scenes that goes into your work. Thanks for sharing!
There should be a youtube feature to remind me to rewatch such excellent videos after say 3 months, this is that good.
There are few things I find more interesting than listening to someone talk about something they're very passionate and knowledgeable about. This video hits that nail on the head.
That was one awesome photography lesson in 15 mins. Real simple explanation of each parameters... Gavin you are an excellent teacher
Best clear explanation of the relationships between shutter/angle, frame rate, aperture and iso/gain in practice I've seen. Nice!
It's fascinating to hear about this because I used confocal microscopy during my graduate studies and many of the principles you mentioned are more or less the same. One difference is that in confocal microscopy, when closing the pinhole, we are actually able to reject light from outside the focal plane, which for our applications where we want to see a specific layer of a cell is very useful.
But what is very similar is the notion of the compromise between speed and brightness of the image. In microscopy, my professor called that the "triangle of despair." Basically, you can imagine 3 points labelled resolution, speed, and brightness in a triangle shape. For any single microscopy, you can draw a straight line linking 2 of those points, but you will inherently sacrifice the 3rd. So you can capture very high resolutions images with good brightness for a good signal to noise ratio, but if you're going to need to let the image exposure for a really long time.
Which in normal photography is okay, just throw huge studio lights at the subject or use sunlight. But for our samples, the problem is that the fluorescent proteins we use will bleach under constant exposure to the lasers which we use to activate them. So it's always a compromise to get the best image possible given the circumstances.
And I bet you we could speak with astronomers and they likely will talk about the same thing, even if their objectives are measured in metres rather than milimetres.
One question, is the concept of numerical aperture at all relevant for "normal" photography and videography? It's a key factor in choosing microscope objectives but in normal videography, I feel like it might not be relevant.
Dude, that was one of the best explanation vids I've ever seen. It really shows how much you love and understand your craft. Even tho it was about slow motion, you just made everybody understand how filming works a whole lot better. Even for me who already knew the basics, you explained it in such a way that it enlightened me even more.
For the first time, I did not fall asleep during a lecture... What a lovely teaching... 😍😍
the quality of information delivery and how approachable the material is exceptional
Thanks for posting this Gavin! Concise, yet loaded with information. Look forward to more of these "waffling on about" videos.
This was the best explanation I've ever heard for photography and videography. It all finally makes sense.
I really enjoyed this. My boyfriend is studying in the photography and film industries right now, but he's not always the best at explaining things to me, despite my want to understand. Gavin, you always do a superb job at explaining how things work in a way everyone can understand.
Thanks!
One of the best YT videos i have ever seen.. definitely putting it up in my FAV videos. The explanation to everything was spot on. Really spot on. Man you fucking nailed the video! Nice job.
Thanks Gav, thoroughly enjoyed your explanation. Really adds to my appreciation of what goes into your SMG videos. Looking forward to more like this.
