fantastic tutorial, amazing stuff brother. I have watched many tutorial on color corection but no one was able to clear explanation as you. you cleared my all doubt on color
Hey nice effort to explain all Lumetri has to offer but you've picked the worst example footage. While it is true that Lumetri can operate in 32bit it is not designed to grade HDR data and only works best with images that have all their information between 0-1 range. I'll briefly list why. If you want to test it yourself create a horizontal linear gradient ramp in grey from 0 to 2 float and check your waveform in float unclamped. Lumetri is also greatly limited in the allowed value ranges up and down but is usually enough for sdr data. Exposure: base math works but -2.4 equates to -1 linear math (because the operator is assuming 2.4 gamma). You can verify this with Exposure effect set to -2.4 when assume working gamma in your project settings is also set to 2.4. Setting Exposure fx to bypass linear conversion and a -1 value results in the same. Contrast: Only creates an S-Curve between 0-1 range leaving the rest of the data untouched creating a sharp corner that's unrecoverable. Highlights: Creates a high range weighted S-Curve not affecting 0 area and 1 area again leaving everything above 1 untouched. Shadows: Same as highlights but for shadow range just above 0. Whites: is just the same operator as Exposure but with different values shown as range. Blacks: Lowering blacks creates an inverted s-curve even for video I would never touch it. Elevating it is not as Lift but rather creates a small curve before going linear. The same messy stuff can be seen with the Color Wheels. Shadows operates as Lift when raising but becomes like the Basic Shadows control when lowering so two different maths in one. The rest of the wheels are also limited to 0-1 range. Long comment but just wanted to get this out here. If you'd really need to color grade HDR data you either need to convert it to log first, use a tone mapper like ACES, or compress all the available information to the 0-1 range first and try to grade from there otherwise you'll always leave hard corners in the data and a lot of available information clipped.
Wow, thank you for the detailed explanation! I 100% agree with you; I would never suggest color correcting inside of AE. There are far better and more accurate tools inside other programs. I only use Lumetri when color accuracy isn't important. This is usually when I'm not matching what I'm working on to anything else, and just want access to the controls Lumetri has. Also just wanted to say that you sound extremely knowledgeable when it comes to color correction; you should make some tutorials for the rest of us!
Thanks Jake! However I never said that it is bad to use Lumetri. It's just not a proper tool if you want to manage high dynamic range images because of it's built in limiters. I use Lumetri almost exclusively for my daily color tasks. As long as you know what the controls actually do you can make the right decisions for the task at hand. I'm also not really a talkative person so I'll leave tutorials to people like you ;)
It depends. If you're working in 8bpc then a white pixel will have no color information to balance from. High bit depths can still have color information in those overbright pixels. My technique is to find something in the image that is brightest and should be a neutral color. Sometimes there is nothing actually white in the images so I'll try to find the brightest gray color I can.
Came for the lumetri, jaw dropped after cc environment fx was used. As always top AE Content!
I love your videos and the way you explain. Thank you
Really nice overview of Lumetri effect... precise but still concise. What I like in your vid is the technical explanations. Thanks for that vid !
Underrated to the moon and back, thanks my brother
So much new information and value I got from this video. Thanks!
Brooo hsl secondary is best thing i learned 👀💙💙 now i can make glows without plugins 😈
Gracias hermano por esta serie de tutoriales,estoy mirando todos! Saludos desde Argentina! 😁
Thank you! I really wanted to learn the HSL part
fantastic tutorial, amazing stuff brother. I have watched many tutorial on color corection but no one was able to clear explanation as you. you cleared my all doubt on color
Have been searching a video with perfect explanation n found this great tutorial! Great video✨ thank you so much.
Your videos are amazing
I always knew this effect was powerful, thanks for explaining!
Nice tutorial, lots of details but just what i was looking for...great job!
Thank you for the awesome tutorial.
Nice tutorial and this is a helpful effect. Thanks for sharing.
I have learned tons from your videos, u rule
thank you very nice tutorial, I just missed the explanation of the other scopes to really understand what is going on.
Bro thank you
Awesome tutorial
Thank you so much
how do I save lumetri colour preset in after effects and use it in Premiere Pro?
Nice
Never thought that AE has viewer exposure control! I think that's only available in Fusion and Nuke
but "color lumetri" why doesn't it work if applied to video files?

Ah yes, that makes sense. See, just another reason you're much more knowledgeable than me on the subject 😃. Thanks again!
I thought when you select WB point you need to select a white colour not grey, I might be wrong.

Ayy, first view n comment!
Nice
