So I just realized I was doing my hand motions in the opposite directions the whole video! Yes, I know my rights from my lefts! ETTR should have a RIGHT-skewed histogram, just to clarify. Ignore whatever my hands are doing ;)
I usually shoot in full manual (in order to try to best all 3 exposure principals) but I usually get my best results (even with histogram peaking in the middle) with high iso values(400-800) during day and am from the tropics in one of your previous videos you mentioned something called equivalent exposures but since it's a long process of trial and error I end up going with my current settings(not to miss the shot) is there an app or site that can do the math
5:25 You never explain how to expose "TTR" other than saying not to change the ISO/gain. You use excessively vague terms like "tone" and "tonal sections" around 1:39 . I've been adept at various video chips since 1983 and and especially comfortable with 12 bit color systems since 1985. Yet I still have no idea what you were trying to communicate. Not at all.
I was already exposing to the right without knowing the reason, now I know. Excellent explanation! Btw, superb narration voice mate! Have you taken diction/speech courses? or are you a natural?
I’m not willing to process in post, so I try to do my very best in camera. And shoot JPEGs. Yes I know this limits my creativity. But I’m super busy as a surgeon with no time or patience to process. So is exposing to the right purely applicable to shooting in raw?
Ok, there is a big mix up here: skewness refers to the *tail* of your distribution. A left-skewed distribution has its left tail longer than its right tail, shifting its center (or "peak") to the right, and vice versa for a right-skewed distribution. In a nutshell, when you perform ETTR, you want your histogram to be skewed *to the left*. It's a simple error to spot when you are watching the video, but if you have the video running in the background then it could cause a lot of confusion.
Your content are rich in knowledge.. Thank you for providing us good knowledge... I have 2 request for you. 1. please make some more videos (learning tutorials) on photography and videography 2. Please make some videos on editing and colour grading... Thank you. 🙏
Good video. But digital values are only 2 base vs 10 base, it doesn't change linearity. Noise increase is just the fact, as you said, that very low values are already in the noise. You don't need quantization under the noise floor, unless you want useless information. If bit depth was an issue, we would see 16 bits adc. You find 16 bits in MF because their dynamic Needs it Like I read on the web, full your well 😊 your sensor deserves it. That's all is about ETTR.
Sony has a setting that allows to show zebras - the highlights at a user-set point. The manual says that depending on the subject, it can be set at 70-80 for portraits and set exposure that the zebra SHOWS on the skin barely, or set for 100+ for landscapes and make sure the zebra DON'T show. Of course, this could be tested practically and see the results.
ETTR seems to apply to well exposed environments. But what about low light situations, is it better to increase ISO and thus noise OR is it better to underexpose and in post increase shadows?
Underexposing in camera will only create more noise when brought up in post, not less. Remember that ISO does not cause noise, low light does. The principle of ETTR applies no matter how much light there is available. The trick is to use the slowest shutter speed as possible to let it more light.
It's avoiding that, useful, highlights are not burnt. So you put them on the right of the histogram. You have to check what parts of the image are at the right Two risks, image too dark, your main subject may be too under exposed, too light can cause color shifts, and sensors are not totally linear, Raw are massaged by cameras, and software generally don't work in a linear color space plus curves... are not linear. According to me ettr is fine when you have a lot of time and when the dynamic of your scene is moderate It's a good tool but it's sensitive to errors
This is really the greatest tutorial on ETTR, taking me to the essence and practical understanding of ETTR. I sincerely appreciate your sharing your briliant insight

horizontal flip footage
Very good explanation. Thanks a lot. Regarding the JPEG preview, maybe histogram + zebras can be a good combination what is overexposed or not?

I love this new video format with you in the background blurred out during the animated scenes
Good to know! It is much easier to animate so I think I'll continue this format!
I was already exposing to the right without knowing the reason, now I know.
Excellent explanation!
Btw, superb narration voice mate! Have you taken diction/speech courses? or are you a natural?
I haven't taken any classes just read the script off my telepromter and I guess it mst just come naturally. Thanks!
I Love ur videos, please make some videos showing how to shoot best videos from camera best settings for even night videography
I have a bunch of videos on my channel for night photoraphy, check them out! :)
@@Apalapse I mean to ask what settings to be used to get best out of camera for day and night also video graphy

I just found you. Your video’s are so super helpfull. Thanks so much! Did you stop making them? And also your patreon? Last download is 1 year ago?

Tried to get to your ‘website’ and it seems to be taken over by ‘bad actors.’ Would like to know what the address is.
Great video. I’ve watched a few videos on ETTR but found yours to be more easy to understand. Your visual aids helped a lot. Thanks!
Why do some people over micromanage exposure..................................
I have found that the image on the back of your camera has to be taken with a grain of salt. Good for composition, otherwise can be very misleading.
Shouldn't you be on the histogram rather than on your face all the time?
Awesome! learnt something:))
Why the distracting music?

Nice to see a photo video by someone who knows the science behind photography and is not afraid to present it. Thank you!

Such a good explanation
quick question, would the ETTR rules applies same when shooting for video?
Content with Quality 😍😍😍...
The only photography channel I trust 😊😊
Your video are of another level knowledge 🧐🧐
ETTR is the closest thing to a “hack” that let’s aps-c shooters achieve similar noise levels to a FF sensor camera
Loved this! Found this while on a ETTR rabbit trail, thanks for helping me nerd out!
One of the best videos. Thanks. Would this apply to shooting video?
This was so well explained and to the point, thanks so much!
Very good video, thanks!!!
instant subscribed!
It’s true, when you raise the exposure on a dark area or a dark subject, it gets very grainy
Good video~
Thank you very much !
Sony has a setting that allows to show zebras - the highlights at a user-set point.

good idea! I've never worked with the zebras but they seem like they're a useful tool!
When I do HDR, I bracket.
nice!
i like your videos! i hope you keep making them :)

Thx, great explanation!
Excellent explanation of a confusing subject. Thanks!
thank you
Excellent, thanks!
Great tip! Thnx
is ETTR the same thing as exposing for the highlights?
It's avoiding that, useful, highlights are not burnt. So you put them on the right of the histogram.
You have to check what parts of the image are at the right
Two risks, image too dark, your main subject may be too under exposed, too light can cause color shifts, and sensors are not totally linear, Raw are massaged by cameras, and software generally don't work in a linear color space plus curves... are not linear.
According to me ettr is fine when you have a lot of time and when the dynamic of your scene is moderate
It's a good tool but it's sensitive to errors
Amazing info
Lots of 💘 From India 🇮🇳

fish to the right
