Where color noise comes from is a really interesting story in itself. It requires an even deeper dive into the physics of how the sensor works, along with the computational trickery that takes place in the camera's processor to turn the sensor data into a color image.
I've always had a good understanding of exposure, signal-to-noise ratios and histograms before, but this is the best explanation I've ever come across. I am going to save this link and if I ever run into someone who is having a hard time understanding these things, I will refer them here. Always.....thank you, Simon!!
The best thing to happen to my photography hobby was getting my first dslr. Finding this channel has been a very close second. Thanks for all your videos!
That’s because Simone looks at the technical side of photography and explained it in the most simplest manner. He’s one of the best teachers ever. I love his videos. He just taught me so much.
Great explanation of ETTR. It's worth remembering that the histogram you're looking at is calculated from the JPEG embedded in the raw file. That matters because that embedded JPEG is produced with the settings you have set for JPEGs coming straight out of the camera, so if you've got that set to 'super vibrant' or something your histogram will be lying to you. Pick settings that output a flat looking JPEG. I've experimented with color balances that get my histogram closer to what's actually in that raw data. It works, but the review picture on the back panel looks greenish. Also, if I'm in a situation where there are a few light areas in an overall dim scene I turn auto-ISO off, set the ISO fairly low so the multiplication that happens at readout doesn't blow those areas out.
That is exposing to the left to preserve highlights and then bring up the shadows, useful as well especially for shooting on the go and get more contrasty images. ETTR on the other hand gives you max info on your raw file, for a given scene, to play around.
This is awesome. I remember when digital SLRs first started being affordable and popular. It was recommended to under expose 1/3-2/3 stops to get deeper and richer color.
In 5 minutes, I learned and understood more about this then I ever knew! Your explanations, examples , and clear teaching style is simply best in class! Thanks for demystifying a complex subject!
Seen so many videos about ETTR but never really understood ’the why’ until now. Once again you are teaching an old dog new tricks! Please keep up the great work 👏👏👏
Hi Simon, you gave great explanations and showed how to Expose To The Right. This bit was my favourite when you said, when you captured the Brighter image, you Frozen the Noise Profile of that photo, so when you Darken it again it stays at where you captured it. And including to use Exposure Compensation as well was so helpful to me. I knew about ETTR but didn't fully understand why, And I'm happy that I understood your explanation. A very important thing I learned today that will make a difference in my photography. Much appreciated Simon. 😊
I wasnt sure about using the exposure compensation as that could increase ISO whereas he mentioned the only way to get more light on your sensor was through shutter speed and aperture
Thank you so much for these tips. You are the only person that explains things perfectly. I really appreciate your videos and they have greatly improved my photography. 🙏😊
That was a masterclass of explanation, you made a potentially difficult and confusing subject, easy and straightforward to understand, thank you for video.
your previous ETTR tought me a lot , after many of your video I think myself a better amateur photographer than before. thanks for sharing your tips n tricks
Thank you for another well taught lesson. ETTR makes so much sense; I have made changes to my Canon and can hardly wait to see how the next batch of photos look.
"Will all of this make you a better photographer?" Maybe not, but it's definitely the icing on the cake, which ultimately improves the overall quality of your photos. Improving many small margins goes a long way to accumulate ones work. I'll take anything I can get, especially from you. Great informational video, Simon 😊Even though as a relatively new photographer myself, your videos can at times be a bit technical and might reqiure a few replays.
Very clearly explained as always - and a great method to give a try. There's a lot more good stuff coming out of Canada than just ice hockey and poutine!
Wow... This was so clear. You have a gift of teaching. In 9 minutes you have given many of us more confidence in using the histogram and understanding our control over noise. Thank you!!
Thanks for this helpfut tip. I was out taking holiday lights out side and was greatly upset with the amount of noise. I will be going back out to reshoot those shots.
I really appreciate your intelligent approach to all things photographic. I've seen many explanations of ETTR, but that was easily the best and most-comprehensive of all. I have a question for you. We've all heard of the exposure triangle many times - shutter speed, aperture and ISO. Do you agree that it should be the exposure quadrangle - shutter speed, aperture, ISO, and amount of light? It would seem that the amount of light is equally important, and always adjustable (flash setting, move to lighter or darker area, polarizer, ND filters, etc.).
Thank you so much for this video and explanation. I was aware of ETTR, but about "over"exposing by lowering the shutterspeed or opening up the aperture and not the iso.
I've been using the histogram this way for a while. Since I shoot RAW, which has more dynamic range than the JPEG used for the camera's screens, I set contrast in the shooting profile to the minimum to compensate, including in the histogram. Doesn't affect the RAW file, only the JPEG and displays. Seems to work.
I did an experiment following the ETTR on the gfx100s in raw. And yes the ETTER ( two stops overexposed) version has less noise as evidently comes out brighter. However, I noticed a significant drop in the dynamic range of this in post production,. Once I adjusted the ETTR version to a correct exposure, the lightroom adjustments, shadow and black handles, were maxed out before I could get the same satisfying result, as the normally exposed. If shadows are recorded too bright, it seems there is less dynamic range to pull from in the shadows.So for me, this is a give and take method.
This could be another video itself. The effects of clipping individual color channels (causing colors casts) will not necessarily cause highlight alerts.
Simon is an excellent explainer! In the film era, I was amazed to see how my journo-style photos improved when I began (a) shooting most things at 1/500 or faster, and (b) learned what created a negative with less grain and better tonal range and separation. In film, the same rules apply, but it's ETTL - expose to the left, i.e. expose for the shadows and develop for the highlights. Boring tech: to get wonderful prints with a wide range of subjects on the same roll of Tri-X, expose at ISO 200 and develop in Rodinal 1:50 for 5 min at 68F with 5/30 agitation. The nice, flat neg printed beautifully on #4 paper. A secret of the film era was that high-contrast paper produces much less grain than longer film development times. Sadly, I learned this shortly before photography went digital, but what a joy it was to realize that ETTR was the same thing, only backwards. Hah! Ansel Adams is smiling in his grave.
This might be one of the best practical examples for explaining why noise is not introduced by high ISO, but from lack of light. The photo comparisons are great for that. Usually not intuitive to convey because of the ASA analogies and the typical correlation between noisy images and higher ISOs under automatic exposure.
Your videos help so much and you do it so well to get this under ten minutes. I cannot fully express how invaluable your videos are. Thanks as ever Simon.
I am calling you “The Professor” from now on, I now understand what exposing to right means and I had no clue what colour noise was! Thank you.
That was exactly my thought too! I'll call him also Professor from now on! 😉
Thanks!
If he is the professor, who is hot sauce?

SECONDED!
This is, by far, the simplest and best explanation of ETTR I’ve ever watched or read. Your style of teaching is simply amazing. Thank you.
Wow, thank you!
Thanks! Thats really a good explanation!
Brilliant! Your explanation and delivery are over the top. I'm learning so much. Thank you.

So glad you're enjoying the content!
This is actually very interesting and clearly explained.
Thanks a lot. I tracked this down during various photo exercises in nature and now I see that it has a name and a definition 👌 great video as always.
Wonderful!
Even if your video is not my mother language , you speak slowly, clearly and I understand you perfectly. Great tuto. Thank you. Merci
Good god dude…… you’re a wizard. Thanks for this!
I appreciate it!
Best explanation ever.
Glad you think so!
Thank you a "super sharp" lesson on noise and exposures...👏👏👏
Learning something new (to me) today. Happy times. Thank you, Simon.
My pleasure!
Now I understand the benefits. Thank you so much for the detailed explanation.
Glad it was helpful!

I had heard that you should under expose by 1/3 stop, but after this, I'm not doing it anymore. Thanks for the clarification about what's going on.
That is exposing to the left to preserve highlights and then bring up the shadows, useful as well especially for shooting on the go and get more contrasty images. ETTR on the other hand gives you max info on your raw file, for a given scene, to play around.
He really outdid himself on this one!

@@simon_dentremont I appreciate your dedication to the craft
The excitement in Simon’s voice when revealing that you can crush the noise in post 😂😂😂
This information is pure gold!! Thanks.
I'm glad you found it helpful!
Pure gold! Thank you!

@ with out your video I’m still stuck somewhere and you’re good level
Oh ding! A real lightbulb moment! Literally and metaphorically. Thank you so much Simon!
Glad you enjoyed it!
Hands down, best instructor on all things photography on YT! Thank you!
Thanks!
Great explanations as always. Thank you
My pleasure!
Really really a Pro 🎉🎉🎉
Thank you for another well taught lesson. ETTR makes so much sense; I have made changes to my Canon and can hardly wait to see how the next batch of photos look.
I hope you're thrilled with the results!
Fantastic detailed explanation Simon. Thank you for taking the the time to share.🙏
This is, by far, the simplest and best explanation
Expose to the right. That's definitely something useful I didn't know! Thanks, Simon!
This is a perfect explanation of how to "embrace your highlights"! Thank you, Simon!
"Will all of this make you a better photographer?" Maybe not, but it's definitely the icing on the cake, which ultimately improves the overall quality of your photos.

Great informational video, Simon 😊Even though as a relatively new photographer myself, your videos can at times be a bit technical and might reqiure a few replays.
Great explanation. The principle is similar to the way old analog audio noise reduction systems functioned- Dolby and DBx.
It's all about managing the signal to noise ratio
Great video on this topic Simon, you are a fantastic educator 👏
That was crystal clear, just acquired new knowledge. Now I couldn’t resist to subscribe. Thanks for sharing your knowledge.
Glad to have you aboard!
One of the most helpful videos I have watched on exposure.
Very clearly explained as always - and a great method to give a try. There's a lot more good stuff coming out of Canada than just ice hockey and poutine!
Right, eh?
You just won a new subscriber. Wish everyone would explain as nice as you do. Thanks "professor"! ;)
The best explanation of the benefit of employing ETTR. Thank you
Glad it was helpful!
Great video! I am a hobby photographer for the past 7-8 years and I have never heard this term on RUclips. Thank you 🙏🏻
Glad it was helpful!
Finely!! I get it!! Never been explained like that before! makes sense now! Thanks
Glad it helped!
Thank you! This is by far the best video on ETTR that I have ever seen. I cannot wait to try this out.
Another magnificent video! Thanks Simon.
Many thanks!
Monsieur d'Entremont, you are the best. Thanks for making these great videos.
Thoroughly enjoyed this one. I swear your videos are one of the few I find myself rewinding rather than skipping ahead! Thanks so much for the tips!
Glad you like them!
Great tutorial, makes total sense, thank you.
Glad it was helpful!
Superbe video démontrant très clairement l'effet désiré avec le ETTR. Merci beaucoup M. Dentremont.
De rien!
Simon, excellent video one of the best explanations on this subject I’ve come across! Thanks

I’d add light and drop iso and keep it a triangle!
@@simon_dentremont I'll have to think about that one.
must in studio, great n simple and slow changing environment.. stay on the save side in Shows, Concerts, and Theater..
Best explanation of exposing to the right!! The "why" always helps to understand the "what".
Thank you so much for this video and explanation. I was aware of ETTR, but about "over"exposing by lowering the shutterspeed or opening up the aperture and not the iso.
Your videos are so reminiscent of my engineering days! Very nice explanations Simon!

Interesting. If there wasn’t any clipping, it should have had better dynamic range. Note that all colour channels won’t clip at the same time.
This could be another video itself. The effects of clipping individual color channels (causing colors casts) will not necessarily cause highlight alerts.
Thanks Simon, I will include this tool in my photography. You made this easy to understand.
