Добавлен 12 апр 2018
Hi there, my name is Greg, I'm a UK-based filmmaker, I run a production company called SHAGRAL. This channel is where I share my opinions, tips and reviews on everything related to making images. Feel free to get in touch with me via email address below. Cheers!
I tried Steadicam for four days. Here's what's happened...
Back from the four day Steadicam Silver Plus Workshop by Tiffen, Greg shares his experiences flying the legendary camera stabilisation rig for the first time. From fitting the vest, adjusting the arm and balancing the sled to Don Juan, Low mode, Rickshaw hardmount and much more fun stuff - all under the watchful eye of some of the best and most experienced Steadicam operators. Now, was it worth the price of admission? Watch till the end to find out.

Image Quality Is DEAD. We Need THIS Instead...
Просмотров 6 тыс.Месяц назад
It's harder and harder for camera companies to compete on image quality these days - because you can get cinema-grade digital capture for relatively cheap. What will set newer cameras apart is the degree of freedom and control over the sensor - how it's used and what's being recorded.

The Problem With Box-Style Cameras... (FX6 / C400 / Komodo / Pyxis / Mavo)
Просмотров 985Месяц назад
Starting with with RED DSMC2 cameras have been evolving into a box-like shape: Sony FX6, Canon C300 and C400, RED Komodo, V-Raptor, Kinefinity Mavo cameras and even Blackmagic Design caved under pressure and released a box-like Pyxis. Even Alexa 35 is ARRI's boxiest camera ever. There's a bit of a love-hate relationship with this style cameras. In this video Greg discusses pros and cons of that...

Unlocking the Secrets of Native ISO & LOG Exposure
This is fantastic 🎉
Thank you!
might wright my dissertation on this after watching this
a dissertation on dynamic range - how cool is that!
2026 😂 A lot of time for BM to make new recorders.
You are referring to the Sony firmware roadmap, but as far as I understand nothing needs to be done on Sony's side, the camera already puts out RAW, it's the recorder needs to be updated. No clear info on that yet, but we'll see. Oh and I made this short a month ago lol
@@shagralit showed me uploaded 23 minutes ago when I commented 😂 WTF Sony released a roadmap a few weeks ago for this and stated 2026 February. 2025 September for Fx3.
Man, really lioke your channel, subsribed! Have to digress about your part on braw, its smaller (12:1) and (18:1) then any of the prores options, also smaller then all-i and many of the H264/h265 options out there, but you get all the benefits of 12bit raw and also one big thing working with braw or any other raw format includin all all-i and prores options is consolidating projects for archiving or later review of grade, with or without frame handles. doing mostly music videos, commercials and narative work, i find consolidating projects with long gop formats in projects is hit or miss, at least few of the clips have fewer frames and you get offline media in the middle of the clip in a timeline. only workaround is to convert all long gop clips to prores/dnx HQX and relink that files to timeline and consolidate from them. which is a pain, and time consuming.
Braw is great, and as a Davinci-based editor and colourist, I have no problems with it. It's just as cameramen we sometimes need to hand off footage and BRAW is not a widely accepted as industry standard codec, while ProRes is, and h.264/5 also, it's just how it is. Having options is always better than not having them. I would hate to have to transcode a terabyte of footage just because a client doesn't want BRAW. But anyway, it's not the biggest deal in the world.
Love what you say on the final
Bravo! Probably the most informative and honest video on YT about video camera technology. Great illustrations and clever humor bits help retain the attention all the way to end. Thank you, look forward to more of your videos.
Thanks! Glad to have you here.
Exactly! Box cameras are great if it’s going to live on a tripod or if you absolutely need specific accessories for your project, but I bought an fx3 because it has a fan, nice screen, good battery life, autofocus solution, auto aperture solution, and great onboard memory options all built it. It’s a self-contained unit that can give me cinema camera quality in my pocket, or I can rig it out if needed.
It'd have been better if you could share the math of squeezing 12 DR into 10-bit bucket, what's stopping the camera from squeezing it into 8-bit, less resolution? if so, for same resolution we can get 10 stops of DR, but tests show 11+, are those extras internal camera shenanigans? And it'd been nice had you demonstrated "contrast filtration" you mention.
Just randomly stumbled on this amazing video. No previous exposure to any of this stuff, but was riveted by the drama. Obviously I see parallels in other areas of life, human nature seems to mean we often obsess about the wrong things. Very well executed.
"it looks like dogshit" 😅 😅
Great video! Very informative. Of course for smaller cameras you can get cheaper rigs around £300 like FLYCAM
Another way to put it, the cinematographer creates the scene by controlling the light and the camera only captures it. 'Why do cinema productions with the most expensive camera use so many lights?'
I learned more in this video than my last 6 months on RUclips, or even last year. Thank you.
Glad to hear it!
Amazing job! Thx you!
Glad you like it!
Don't worry about dynamic range. It's irrelevant. Make a movie that rocks the world like Citizen Kane. In the movie reviews nobody mention dynamic range range there. Same is true for terminator 2.
I need to put on my Red fanboy hat and ask you why these cameras are in the same bag as mirrorless in your video? genuinely curious, the power draw, thermal envelope, 16bit in 14?bit container? I get it that these cameras can be a bit of a let down on the current market, either spend significantly less, get a sony and cater to clients that don't care about nuanced look or if they do you need to spend a bit more and get an Arri anyway. But if we are nerding out about camera design something like komodo-x should have some upper hand over mirrorless, why it's not perceived as better?
They shouldn't be thrown together in the same bag, that's what I'm talking about - 26:17 Imatest is used as a catch-all metric to compare cameras that shouldn't be compared. Komodo-X can and does have upper hand over mirrorless, just not in the dynamic range department. It mostly comes down to the RAW codec, which remains the #1 selling point for RED. And I have to say with global shutter and after the price cut, it's a very attractive camera. And now with RED being under Nikon I don't hate them as much haha. But still they are not the best investment or value. Like you said yourself, they are in that weird space where I'd either go for the best/industry standard (ARRI) or best bang for buck (Sony) or cheapest (Blackmagic) with RED not fitting anywhere.
Such an informative and useful video, thank you for putting this information out there for all of us who are less informed. Matter of fact, that goes for pretty much every video of yours i've seen so far. Also as some have touched on already, great delivery as well. The way you explain these things finally makes sense to me after wading through so much information that is either just wrong, doen't make sense, or is poorly presented and hard to wrap my head around. Comedic touch is also much appreciated. As I really only shoot photography and have very little experience or knowledge of video, I have a question about your advice to not shoot in LOG if you are shooting a dark scene with no ability to add light and therefor must turn up the gain. How would this pertain to shooting still photography? At that point would it be better for me to shoot jpeg rather than RAW? maybe i'm drawing a connection between RAW and LOG that just doesn't exist, hopefully you can enlighten me on best procedures in this situation... also one other thing to perhaps mention is i use a Fuji camera, so its in fact not a Bayer sensor - a topic which you mentioned at a different point in your video - but I have no idea whether this makes a difference either. If you have time to respond, I want to say thanks for taking the time to explain some of this to a novice like myself. If not, then I understand. Either way you have gained a subscriber and looking forward to your future content
Hey thanks for watching! Not sure I understood your question, but there is no LOG gamma in still photography, as it is not needed (apart from HLG). As for ISO, when shooting RAW stills ISO is only saved as metadata and photos will require noise reduction in post if underexposed. Shooting jpg (or better heif) is definitely an option when you need fast turnaround. But RAW as a backup is always a good idea. In terms of what ISO still looks OK in jpg/heif - totally depends on your camera. Do some controlled exposure tests at home and you will find the breaking point and the exposure sweet spot. With most decent cameras you can go 3-4 stops under native (if native is ISO100, then -3 is ISO 800 and -4 is ISO 1600) and still capture a decent picture. Dual native ISO works in photo mode too. Fuji's pattern is not that big of a deal, it's still a CMOS sensor with a colour filter array, just a different pattern. And as I understand in case of X-Trans it was a mostly a cost-cutting measure - so they could avoid putting an OLPF over their relatively high megapixel sensor while still reducing aliasing. I don't own Fuji myself but I've seen reports of weird artefacts (pink teeth and sclera) caused by that pattern in some edge cases.
A little bit of Tarkowski .... greetings to Russia from Germany. Just a question for me, would more realistic colors look worse?
It's a matter of taste, of course. For me, definitely would look worse. Colour is an expressive tool, the look helps create the mood, which supports the theme, all important parts of storytelling. Why would I discard one of the strongest tools? Besides, I would put forth that there's no such thing as "realistic colours". Everything you see is graded heavily (even for "realism"). And cinema is built on 100 years of analogue film, which definitely doesn't have realistic colours.
Excellent video dude. I want to switch to Mac but I'm scared of the jump. I already use iPhone and IPad but scared shitless to exchange my PC for Mac simply because I see my self as a super excel user, my work involves working 70 to 80% on excel spreadsheets. If I have to now change they way I work in excel (shortcuts and custom banners etc) I may regret it big time. Again very good vid👍🏻
Thanks for watching!
Where are you getting the generalization for 12bit = 12 stop and 8 bit = 8 stops. Why not say each bit is a stop then 8bit = 256 stops?
I should have been more careful about phrasing that, and a lot of people jumped on that (deservedly so). Of course there's no direct limitation of the number of bits to stops, but it also shakes out in practise that way, that 12-bit readout cameras all have under 12 stops at SNR=2 with patch range (total DR) of about 14 stops. 12-bit readout limits how well you can see into that noise, thus limiting usable DR. I'm happy to be proven wrong, but so far nobody pointed me to a 12-bit ADC camera that has 14 stops (or even 13) of DR at SNR=2. AFAIK they don't exist. So the conclusion stands, even though I messed up the reasoning. I've pinned a comment chain by Alister Chapman, he goes more in-depth on this.
I was frustrated with most of the exposure tools on the market and created my own zone system inspired by Ansel Adams. I have heard of EL Zone but never looked into it. Thanks to your video I realized I basically recreated it... :/ Anyway, it's basically an FX6 / FX3 LUT that I leave running on the small screen while using a dedicated external monitor / raw recorder for composition. Let me know if you're interested in checking it out. Cheers!

Imho the classic broadcast body is still the best for ergonomics. Amira is close to it but it’s pretty heavy and not necessarily as easy to operate. The reason why it was once popular is the sensor not the ergonomics. Blackmagic was sporting “eng-style” for all their high end models until very recently. However, the design is nowhere near of the actual competition. Why can’t we then innovate away from this once proven design? Well, while the sensors and media has changed, humans are still the same, two hands and a head between.
Great video, yet again.
Very interesting. Some nerdy details I already knew, and some I had no idea. That video is a lot of work. Thanks for that! ;) Regardless of all that, I do look at numbers (mainly CineD Lab Tests) when I'm looking to upgrade camera body, just to give me an idea, but I always judged DR by eye, based on my experience with the previous camera I owned. I also ALWAYS use a precise LogC conversion taylored to the sensor of my camera (Emotive Color), so all of the cameras I owned since 2017 had the exact same colors. That way, it's very easy to notice other aspects of your new image. Does it feel like I see more in the shadows when exposed for the highlights? When I switched from the GH5 to the BMPCC 6K, the extra stop of DR was VERY noiticeable. When I switched from BMPCC 6K to the Lumix S5, I didn't expect that much of a difference since IMATEST only showed 0.3 stop difference.. but i was wrong.. it was still noticeable in some shots, especially when shooting a very high dynamic range scene, like in the woods, where there are strong sunlight piercing the trees canopy and very strong shadows. From S5 to S5IIX, I haven't noticed any difference, since it's pretty much the same (0.2 stop difference based on CineD's IMATEST). We could also just say that most modern cameras have enough dynamic range to meet most requirements, that people should learn how to ''use/control'' their dynamic range instead of obsessing about the numbers. Camera manufacturers should now focus more on improving where it truly lacks, compared to the competition's equivalent. Still, we all dream of being able to shoot indoors with only natural light, expose for shadows and not having blown out windows.. and people aren't going to change until it's achieved. You can always blew them out in post if you want to. Not that there's anything wrong with blown out windows though. We're used to see movies shot on 35mm film, and there was still lots of blown out windows. They could have used ND gels, but they still choosed the embrasse the windows as speculars.. indeed as an artistic choice, and it can be beautiful/well desired. So I definitely agree with you... use your eyes and artistic sense, and just create! We absolutely do not NEED more DR that those affordable mirrorless cameras can offer in 2024, and even though I would gladly take some more.. I wouldn't replace my S5IIX for extra DR alone, that's for sure. Creating a clean highlight rolloff, smoothly fading to pure white, is extremely easy on ANY camera. You just need to taylor it to your sensor's response (where the highlights RGB channels start clipping unevenly). You simply desaturate this area and smooth out the top of the curve. Yes, you will technically loose this ''useless/ugly'' highlight data, but your image will look much prettier and film-like/Alexa-like.

this is exactly why my next camera will be a Z200. i'm getting off the ride.
I have a question about the ISO on my Z Cam F6, which has a dual native ISO of 400 & 2500. When I shoot a scene that is properly exposed at the base ISO of 400, I notice it has more noise compared to when I ETTR at a higher ISO, like 3200. Why does this happen?
Short answer is: "working as intended". F6 uses the Sony A7III sensor if I'm not mistaken and it is a bit noisy and requires ETTR if you want to get squeaky-clean shadows. However, Z-Cam are good at recording a more pristine noise profile with minimal NR and sharpening in camera, so it should withstand NR in post with minimal degradations in quality. It does require more work in post, but that's "cinema cameras" for you. If you want clean shadows out of the box, use ETTR. High/low ISO are almost equal in terms of noise, biggest factor here is ETTR or not. Edit: oh, and do some tests! set up at home in controlled environment and cycle through all the ISOs, over/underexposing and study what happens when normalised in post. That's the best way to find and see the exposure sweet spots // breaking points of your camera. Learn your tools!
@ Thank you for the info. Definitely will do some exposure test.
Holy cow, I needed this. You have a new sub.
Thanks 🙌🏻
This is one of the best videos on the topic. Hats off! As a VFX professional approaching hobby cinematography I quickly realised how the cinematic look was influenced by the limitations of the filmstock and the creative workarounds DPs came up with to manage the scene contrast before if was recorded. But it's expensive to achieve. People these days think they can slap a LUT on a crappily lit scene and expect magic because 'dynamic range'... LOL But i also realised the problems with uncontrollable saturated light sources when doing run-n-gun , namely street lights and car lights which have become much brighter due to LEDs being used.

@ very informative video with a lot of details. Nowdays fake DR claims are horrible, just marketing scam hehe. Good that more and more people talk about it out loud. “I nee more dynamic range” is what I hear mostly on RUclips. 😅
Great job!!! This must be the most no-nonsense video/cine/imaging tech channel I've seen so far, and I've been through lots of them that were mostly wasting my time and others. But... One thing I've met oh so often - why 'negative amplification'? There is a specific word for this, and it's called attenuation.
Makes sense! Like with microphones.
It's like with anything involving electrical currents or fields. It's a legitimate term, that noone - in the realm of the popular imaging videos at least - is using. Maybe 'negative amplification' sounds more catchy, bombastic, tabloid-style. Good ole' Carlin was so right on bullshit language.
The best video on the subject I've ever seen so far.
Thanks!
i feel like there is a whole spectrum of its own within the world of computational photography and its dynamic range capabilities. but as a standalone for a simple breakdown of most of the important factors of hardware photosensor equipment this was very well made and commendable have a great day <3
Thank you!
43:35 At least yours is a sweet potato. I'm still shooting on a regular Russet. Might do the baked mod though.
Where to start: Photons - yes there is shot noise in light but most of the problematic noise in a video system comes from the electronics. It's only when you get to extremely low light levels that the randomness in light starts to become a factor. Photon shot noise only increases by around 1/2 a stop for each stop you go down while the effects of read noise doubles for each stop you go down. So in the deep shadows the read noise from the electronics is almost always more significant than the shot noise. The number of photons hitting a photosite during a typical exposure is not in the thousands, it will be in the 10's of thousands and the amount of photons needed to result in a full image well in a typical modern sensor is closer to 100,000.
Dynamic range from the top of the well can and often is manipulated. In a dual ISO sensor the full well capacity is increased by adding an additional capacitor for the sensitivity range, this shifts the sensitivity down by the image well now needing a lot more photons/electrons to fill the well. There is no reason why additional capacitance can't be added in other sensor designs to increase the highlight range of the photosite. But there are other bottlenecks such as the maximum voltage swing that the emitter follower can handle or limitations in the ADC.
The least amount of noise would come from sensor run much cooler than 40c. A cold sensor will deliver less noise than a warmer one. But it is very difficult to run a sensor below the dew point of the environment the camera is in without condensation forming. Additionally it would require a lot of extra power to actively cool a sensor to below the ambient temperature. So, sensors are typically allowed to run at at least 40c as it is easy to use variable speed fan cooling to maintain a temperature higher than most normal operating environments. Many cameras take the air that is used to cool the electronics and then pass this already warm air over the sensor to quickly bring the sensor up to a constant temperature. This is more electrically efficient than trying to use a peltier device to regulate the temperature. And the majority of cameras no longer need black balancing.
There are many ways to allow a 12 bit ADC to record a dynamic range greater than 12 stops. The source follower buffer between the image well and ADC can have a non linear response. The use of non-linear ADCs on CMOS sensors has been common for a long time as has the use of Floating Point ADC's. Sensor manufacturers are often very secretive about the processes they use, but there are plenty of well established ways to get a lot more than 12 stops from 12 bits. The 12 bits ADC can only 12 stops argument simply doesn't hold water and there are plenty of camera tests that prove this. Where 12 bit is limiting is not the range of stops but the precision. Precision is important because you want to be able to record the sensor noise as finely as possible. If the ADC is too coarse, the noise will be coarse and separating the noise from the smallest stops becomes more difficult and as a result you get a poor SNR. A deeper bit depth would allow the noise to be recorded more precisely allowing for smaller lower stop levels to be discerned or used. So, a 12 bit ADC won't generally allow you to go as far into the shadows as a 14bit ADC. But the total Range may be the same. But there are a lot of other factors that affect noise such as screening and filtering, management of noise in the power supply etc, so why a 12 bit ADC will tend to limit the useable range and a s a result many similar sensor designs will perform very similarly it certainly isn't the only factor to be considered.
If you plot linear gamma using a log scale (stops) on one axis and a linear scale (code values) on the other then of course you will get a curve. Change the log stop axis to lumens and you will get a straight line. The reason your charts are counter intuitive is because you are mixing log and linear scales on the same chart.
Log gamma isn't almost lossless, it actually very lossy, don't mistake the concept of "visually lossless" with what is actually going on, with log huge amounts of data is being discarded, data that can never be recovered. And it's not just highlight data. Most log implementations use power law gamma up to somewhere around middle grey and then become log at middle grey. If they didn't have the lower power law curve at the bottom there loosy nature of log would result in insufficient mid range date for a decent image. Go up 1 log stop from middle grey and you only have half as much tonal information as you could have, 2 stops up and only a quarter - these aren't highlights, this is the mid range where skin tones etc are, even a normal power law gamma such as Rec-709 will give you more mid range tonal information than log (at the same bit depth for both). If you do work with high bit depth linear material you can see a difference in the highlight textures, especially if you are doing an exposure shift. Log is a fairly big compromise, it is very lossy.
Yesterday I was on a shoot and the Sony Monitor and camera app was kind of a nightmare, and I was just trying to use 1 camera (FX30) and my iPhone. Took me forever to get it connected but once I did it worked until I turned off my camera or closed my iPhone. When starting my camera back up it would always give the failed to connect to the camera warning and then I would have to fiddle for over 20 minutes trying to get it to connect again. Cannot remember what sort of worked but basically kept having to turn off bluetooth or remove the camera from the app other wise it would never pair even after pairing the first time before I shut the camera down? Any body have success getting it to work properly or what the exact way is to get it working and keep working automatically every time I want to use it or turn my camera off? Seems pretty useless if just turning the camera off makes this happen? Thanks !
That's exactly what I'm talking about in the video - the app is not ready for professional use. What little help I can offer you: make sure you have the absolute latest everything - camera firmware, app version, ios version. If at all possible, try having a separate device (ipad works best) that you don't turn off or fiddle with during the shoot.
@@shagral Thanks, I just have an older iPad and used my iPhone 14 pro max yesterday and have all the latest updates. I just want to use it so my assistant can press track focusing when I need it. I cannot believe it cannot remember the connection when Turning off my camera and back on. Such a simple thing. I guess I will have to give Monitor + a go again bc even though it loses connection sometimes it does automatically regain access with out fiddling with all the connections like wifi, etc etc every dang time. It is like I have to un pari and repair my FX30 every time , otherwise it never connects and get a failed waring check my camera settings etc etc... Totally bummed.
This video is incredible. Great work. I’m now better off for it.
Great to hear!
Definitely one of the most important video to watch for all camera nerds to escape all the marketing bs. We often chase the latest cameras with high chart scores and end up not using their full potential.
Thank you
great work
Another great one🎉
Absolutely awesome explanation, great editing and animations too!
Glad you liked it!
whoa a camera tech video that is accurate understands the subject matter
Very interesting video, thanks! I have some questions... so the analog to digital conversion point I'm guessing was solely for discussing the sony A7siii and its marketing trick? It seems like from what you said that log circumvents the 12 bit dynamic range limit. Also another question about photos - the photos I've shot in my camera's 12 bit electronic shutter mode have a lot more dynamic range than the 10 bit log video files. How could that be, if the camera only has one data value at the darkest shadow stop?
Fun Fact: that motorcycle shot you used as an example from The Creator was shot on a Nikon Z6!
Yes I remember now, it was shot during the location scout for a proof of concept reel and ended up in the final movie Edit: @owlbot didn't notice the user name at first. Hi Kenny! Love your Frame & Reference podcast, great work. Hope you enjoyed the video.
@@shagral Oh wow thanks man that means a lot. I absolutely did enjoy the video, you certainly put more work into making education fun than I do LMAO! Your production value is up there with the best on this platform
@Owlbot thanks Kenny 🙌🏻 looking forward to the episode with Greig Fraser. Hope he finally got himself a decent microphone 🤣
@shagral man you know the show, everyone's on airpods and then I do my best in post 😂
@ I find it hilarious that these top 1% of DPs can't invest a couple of hundos into a decent zoom setup. I mean they do these calls all of the time
Google sent me here.
Google finally doing something right!
