What’s your favorite way to use distorsions creatively? Let me know!
Sometimes in Lens Corrections, I've used the "distortion" to deliberately zoom in (slide left), as way to zoom into my subject but still have most of the photo background. It's a way to get a distorted wide angle effect without a wide angle lens :)
A very large building seen from very far away through a telephoto can make it impressive because it becomes proportional to other objects nearby. Wide lenses might fit everything in but it pushes back and shrinks your object. Distortion is always distracts from the subject in my view. Just a “normal” guy I guess.
Fisheye really up close!
Perhaps one of the most striking effects is with crowds. Shooting with a long lens from further away makes crowds look much more busy, more 'crowded'. News outlets of questionable credibility use this to manipulate stories, like e.g. during Covid they'd shoot long lens photos of people at Melbourne's beaches to supposedly show how they aren't respecting social distancing rules, while people's phone pictures would show everyone well separated, individually or in small family groups.
what i genuinely love about this channel is that he never talks about equipment. only techniques and instructions. thank you for all this info.
Thanks for the kind words! I’m all about technique and understanding.
Realtors taking pictures in houses - So anyways, i started blasting with a 10mm
With refrigerators and ovens looking 6 feet across…
There's a whole art to real estate photography. Tripods, multiple shots, multiple shutter speeds, flash and editing, lots of editing. That will get you the best images. But I remain amazed how well a cell phone image will look in a listing. I'm torn on this issue as I purchased a wide angle and shot real estate for a few years. I still enjoy the lens for outside photography, I want to try astro-photography next.
Dear Simon, this is the best explanation I have seen ever! I really do love the way you break things down and structure your videos. Excellent stuff as always. Paul.
Glad it was helpful!
Yours is the first photography channel I have found to explain topics in sich an engaging and concise way. Every video gets me more and more excited to shoot some photos!
Did you ever have a feel for how something worked from experience, but then you heard someone explain it well and it suddenly, despite you having a feel for it already, feel like you understood it so much better on an intellectual level? This just happened for me. Thank you.
Oh dear. Another video that I'm going to have to watch over and over and over and over and.......
I started out saying to myself, "no, no. NO! Not again" until around the 5 minute mark. Then you turned it around and I was able to breathe normally again. Thank you! All lenses give the same perspective from the same camera position. Focal length changes magnification, which changes the framing. Back in the day it was drilled into my head to pick the camera to subject distance to give the relationship between the elements in the scene (perspective), then pick the focal length to fill the frame appropriately. Don't blame the lens. Cheers!
Hugely helpful explanation, Simon. If you ever get tired of photography, you could absolutely be a teacher, because you have a great talent for making things make sense for laypersons.
Wow, thanks!
I picked up a Fujifilm 8-16mm a few months back to do astrophotography, but now I end up using it for pretty much everything else more just because I like the challenge of shooting so wide! Good stuff Simon!
You're a real gift to me. Keep up the good content 🙏🏼❤
Thank you Simon for helping this amateur learn a bit more of the craft of photography.
Glad you enjoyed it
Simply the best teacher👏🏻
He is good, with a very easy going style.
Absolutely excellent explanation. So many people get this wrong
Love this, every time you post a video about a topic I think I understand, I end up learning something new!
I would love to see a video about how distance and focal length affect depth of field, I can tell there's something going on when I go from very close up subjects to very far away, but I'm having trouble wrapping my mind around it. especially for astro-landscapes where my aperture is wide open and my subjects farther away
done. ruclips.net/video/6LuvQdGXb4M/видео.htmlsi=hZs5Kws_CuCA9z_n
Understanding something and communicating it to others to help them understand are very different things. Your ability to communicate complex technical concepts/ ideas (with examples) to others so fluently is exceptional. The fact that you seem to enjoy the process is perhaps of equal significance!
Really nice to see so many appreciations in the comments section. Many thanks, Simon
Thanks, appreciate that!
You are a great teacher. Concise and to the point!
Glad it’s helpful!
This might be the best photography video I've ever seen. I know this took a lot of work. Thanks, sir.
I appreciate that!
Thanks, Simon. You corrected at least one myth I had in my brain about focal length and compression distortion, plus, you also explained "Guided", which I had no clue about before this video.
I’m glad it was helpful!
Great video! This is something I’ve always known as “perspective compression” and as a street photographer it can be very useful. I live in London UK, and to take photos of the Xmas lights down Oxford Street use of perspective compression means the distance between one set of light displays and the next going down the street becomes compressed together giving far better composition!
Absolutely!
This was a great explanation! So much to learn with photography, so I always appreciate these!
Thanks for watching!
how does youTube shows the comment 4 days ago when the video was just posted? I dunno this algorithm crazy
@@gezimislamaj5309 Sometimes, if a video is in a playlist before it goes live, it can be visible if a viewer is in the playlist. I was surprised to see it was the first view! But as someone who uploads to YT, I have seen this happen before on my own videos.
The Lens correction tip is incredible. Thanks Sir.
A brief, highly technical discussion of some common effects in photography that ultimately left me feeling dumb, though I often work with these concepts / effects on an intuitive level. One doesn't necessarily use these effects in an intentional way but rather works around them, given the circumstances of a situation. Perhaps someday I'll arrive at a sufficient grasp of them to be able to discuss them more fully, but it is not this day. Thanks, meanwhile, for a thoughtful, well-produced presentation and for providing the term "compression" to name the phenomenon to which it refers, not limited to photography.
Thanks for the excellent explanation and wonderful examples. I feel like I only partially understood this topic before, but now I have a more fundamental idea about what is happening. Subscribed.
Bravo! With some knowledge, a photographer can move from being a “lazy bones” stand in one place and zoom to fill the frame photographer to one who understands how lens optics and subject distance can be used to tell more powerful stories. Thank you, as always, for your excellent tutorials.
Now I'm going to have to watch this again with my camera and lenses to repeat what you showed. That will be the best way for me to learn these concepts.
Never knew about that last trick, or that cropping leads to more compression. This was a fun watch! I knew most of it, but not everything!
Amazing video! This phenomenon reminds me of a scientific paper studying distance of photos on phone and the perception our mind to minimal changes. They could even correlate the start selfies to the increasing number of rhinoplasties. Terrifying to think about, especially with people tempted to use phones as mirrors nowadays.
never did bother to look up how "guide" was supposed to work, now I finally know
thanks!
Never even knew compression/distortion was a form of creativity! The more you know! I’ll have to get back to you on this one! Done! ✅
Crystal clear. I don't think there could be an explanation that I'd understand better.
You did it again. This was so easy to understand and makes since! Thank you, Simon
That was the clearest explanation I've ever heard! The animations/diagrams always help a lot, too. Thanks!
Great explanation! The way you break things down step by step is very helpful in learning more complex aspects of photography. I appreciate it!
Glad it was helpful!
Thanks a lot Simon! Your explanations should be used at photography courses.
Excellent description. Always appreciate your clear explanations and the great examples.
As always, clear explanation.
Well done, who still doubts that?! :)
I recently watched almost every video on your channel, and now I really look forward to each upload! Thank you, it's been informative and very encouraging :)
Glad you like them!
This was the best video on the subject I've seen so far ❤
I've been using Lightroom for years and never until now did I know how to actually use the Transform tab. Thank you!
You are very welcome!
Great explanation of several features... not just compression
This is great! Seeing the examples is so helpful. Thanks for the clear explanations!
I REALLY appreciate your good old editing style! It was a pleasure to watch :)
This is one of the best explanation videos about the focal length and the distortion I have ever watched . Would you please share some tips on using different focal length on shooting or any interesting image can be made by compression or distortion. Thanks!
Ce que j’ai particulièrement apprécié dans ce vidéo, c’est le fait d’avoir compris comment parvenir à prendre une photo, avec la lune en arrière plan, par rapport à la distance des objets/sujets selon le choix de la longueur focale de la lentille! Maintenant je comprends beaucoup mieux comment mettre la lune en évidence par rapport au contexte de l’image… 😊
Parfait!
Always a brilliant explanation of photographic topic. What I appreciate the most is how the ‘distortions’ can be used! Really great and I enjoyed it much.
Glad you liked it!
Another great illustration of what is actually happening!
That was fascinating. I had never even thought to try compression creatively. You always explain things so clearly! My next experiment! 👍 Thank you!
Glad it was helpful!
Another great edit, Mark. Thanks
Brilliant explanations as always Mr. d'Entremont. Many thanks.
Excellent tip on distortion. I am 95% wildlife, but a friend asked me to take pics of her kitchen 😱. The guided tips are perfect. ( will stick to wildlife)
I hear ya, kitchens are tough!
You are amazing and your tutorials are so clear and understandable and helpful. Thank you!
Thanks, glad you find them helpful!
Love your videos! Even though I am just a hobbyist, l find your videos very informative and educational! Thanks again!
Glad they’re helpful!
Thanks as always Simon. Your expertise on the science of optics and communicating that knowledge making it easy to to understand is tremendously beneficial to many of us. Your technical explanation of how an experienced photographer can make an image like the moon seem very but unnaturally large based on lens, zoom range, etc. was enlightening!
Hello Simon! Happy to see here again! Great tips as always, you're the best!!
Glad you like them!
Thank you for making the physics of photography practical and useful. Always enjoy your videos!
Beautiful explanation of compression with awesome examples, my sweet spot for all general photography is between 50 and 85 mm. Anything wider or zoomed in allows for creative experimental opportunity. Your explanation is spot on!
Glad you enjoyed it!
Wow I always watch your videos with total emersion the examples and explanations are indepth but easy to understand
A great video Simon and a great explanation 👍
Great video, thanks! I've had this conversation a number of times with folks that think their telephoto is compressing the image.
It can be a tough thing to explain.
thanks for explaining things simple. Physics can’t be changed the only thing that affects distortion and compression is subject to camera distance, end of story. I had a guy comment that lens compression was not the same as digital cropping 😂
Nice explanation. It is a very simple experiment everyone can do with a zoom lens, not necessarily long zoom range cos the results are very obvious.
Great work, Simon!
Many thanks!
Nice, overall great video! And now I know how to use that mysterious (to me at least) "guided" transform.
Glad you liked it!
Simon, this is another great video from you. Though I automatically thought this was going to be a Severance post due to the focal length/dolly zoom effect.
Glad you enjoyed it!
Where I live, we have a lot of space launches. With a long lens, you can compress the launching rocket and a foreground element, to make a very cool "forced perspective" shot. I noticed the shot one day on a buddies post, and had to try it for myself. Forced perspective is a really cool tool we get to use. A little tricky at first, but once you get it...
Always great shorter videos that get to the point, thank you Sir! 😃👍🏾
Thanks for watching!
An excellent, simple, clear instruction. Thank you.
Thanks for watching!
Once again great content..the way you explain things is simply amazing
Love your vids -- and your presentation style! Thanks... 😊
What an amazing film to reference, especially this scene in particular. Touché!
Thanks for making these concepts so simple to understand ! Really helpful .
You're very welcome!
New upload day?! Thanks for the content!
You bet!
10 years of Simon's advices and hop you're a professional camera ’holder’😉.
The video is just great, even if I know how it works I just love how you explain it.
Thanks 👍
I am dragging with me question. I think you're the right person to ask it. Before the question; one of your courses cover the this in a bit more optical (physics) approach? The question; 85mm, is considered the most attractive distortion for female portraits. What about a lens which has 85mm part of larger range such as 70-200mm. Distortion wize and other relevant attributes are equaly good for the above purposes?
it depends on the look you’re going for. anything between 50 and 200 can look great. An 85 is amazing
@@simon_dentremont 70-200mm which has 85mm in terms of distortion would be equaly the same?
Thank you once again, this topic was exactly what I needed explanation on
Glad it was helpful!
There are tenured (photography) professors who are nowhere near this good (I know) ... thank you "Dr." d'Entremont!
Wow, thank you!
Great info! This explained a lot. The application that interested me was with smart phone cameras whose focal lengths are thing like “5mm” or “8mm” I was confused why that didn’t result in visibly different compression from my dslr, this video explained it perfectly. If the field of view is the same the compression is the same, regardless of focal lengths!
Best explanation I’ve come across on this topic
Wow, thanks!
Thank you for a very thorough and straightforward explanation.
Glad it was helpful!
Spot on! Accurate & Concise
Glad you found it helpful!
Very clear, helpful and revealing explanation. Thank you!
You're very welcome!
Enlightening, as usual. Carry on. 👍🥂
The perspective distortion comes from tilting of the camera. This is because unlike the retina of the eye the camera sensor is flat so tilting the camera makes it look like the entire subject was tilted. With the eye this does not happen because of the curved retina. Also our brains naturally correct things. This was hard for me to get, I originally thought it was just normal perspective.
If you use your phone then Photoshop Express can fix these easily.
Start your own channel if you are so knowledgeable .
Hi Simon, can you pl make a video about your setup youtube video because the lighting is beautiful, calm and professional.
I was wondering about this a few weeks ago when selecting a lens for vlogging, I wanted something wide that I can clear-image-zoom into so that I have multiple uses from one lens and was confused about how to get a “50mm look” without a 50mm lens. Theoretically by zooming in to 50mm it = the same “compression” (or lack thereof) to 50mm which honestly blew my mind as someone who just recently got his first ever sony vlogging camera :)
This was amazingly helpful, thank you!
Glad it was helpful!
Super beau vidéo, Simon ! Merci !
10:31 Peggy's Cove Lighthouse! Spent last summer in eastern Canada, including several visits to Peggy’s Cove, you certainly live in a beautiful province.
What a fantastic explanation! Thank you!
You're very welcome!
Thanks Simon ❤️😃
Temps hit 52F and sunny here in Minnesota the other day. Got out with the new wide angle lens. The frozen river was difficult shooting video as a polarizer and ND filter together just doesn't work well for me. Liking creative wide angle stuff as I mostly do landscape photo and video. The frozen waterfalls was brilliant at the end with a treacherous climb out. Sometimes the falls is dry, but not this day and we've been in a drought. Thanks for the informative video Simon.
Glad you’re enjoying the wider angle look!
I saw it first! Wait every week for your videos!
Iirc the shallower depth of field of a longer lens is to a significant offset by the distance you have to be from the subject (making the dof deeper). The level of magnification makes the bg appear “blurrier” even though the depth of field and “blurriness level” are the same.
Just the kind of video I was looking for ❤
A true Master Class! Thank you very much!
You're very welcome!
What a nice coincidence. I just explained this effect to people a few days ago with some selfmade images. Now I can link to this video for a neat explanation and examples. :)
Interesting!
Outstanding. Thank you.
You bet!
You are so easy to listen to.
Thanks for a giving a new "perspective" on lens compression.
Excellent discussion
