As a beginning colorist, I don’t know what I don’t know. As always Cullen, you show us what we don’t know but explain the why or science behind why do it this particular way. I was just a knob turner when I first started but watching your videos has made me think About the overall process in a new way. Outstanding video Cullen, outstanding
I can't believe what I'm seeing. I've been watching your last couple of videos that had to do with Linear Gain and my god I've never had this much color and exposure accuracy in my footage. These techniques alone have made my HDR grades accurate. I can't thank you enough!
I work at a post house alongside colorists and your videos really help me feel educated and up to speed when talking with them. The difference between your industry knowledge and dinky youtube grading tutorials can not be overstated. You're one of the rare ones who creates content which isn't just the blind leading the blind. Keep it up!!!
The way I learned it in the past was basically that I was told that Color Correction and Color Grading are two seperate things. Color Correction being the process of adjusting footage in a way that makes it "correct" from a technical standpoint such as adjusting the WB Temp to being 5000K in case it was shot at 3800K, if the light source lighting the scene is actually 5000K. This sounds very reasonable to me. Color Grading (as I was told) is the process of adjusting correct input color in a certain way to convey or emphasize a specific feeling even if that makes the image not exactly "correct" because it exaggerates certain colors or wipes them out or adjusts the brightness of a scene to intentionally become "too dark" because info gets lost in the blacks and skintones are well below the respective IRE amount they "should" usually be at.
I don't think you understand how chromatic adaptation works. RGB gain multiply operation in linear gamma and in LMS color space which is based on human vision (not camera). That's the basis for HDR controls.
Question: Was your timeline Color Space set to the Log Color Space that the footage was in? Because you're operating before the transformation, right? So it would be a log image, and I noticed you didn't change the both color space of the HDR tab, nor from the Chromatic Adaptation effect. I've been using linear to balance my shots lately, it truly is faster and very good, thanks for the tips!
Love this. Very helpful. How would you compare linear gain to using the HDR global ball? I'm teaching this to students and the linear gain thing is probably too technical for them. Would love to know also how you do your gamma adjustments these days.
This method is so cool, nice and concise… You showed this method in a previous video I think as part of resolve con if I remember correctly. In that video, you suggested as I remember, turning off channels one and three along with converting the node to linear. Should we do that?
Awesome video Cullen, thank you for sharing my question is irrelevant but, could you tell us when is the grade school? i remember first it was Friday and then turns out to Monday. and these days i always check community note and channel but no news about grade school :(
Just rewatched it. His question is warranted. Yes, Cullen has recently talked about using the Gain wheel in Linear Color Space. He didn't elaborate on his motivation though.
I've heard of you talking about Linear Gamma Gain. I'll be honest I don't really understand. Could you please point me towards one of your Tutorials that explains this process please? At the moment my preferred weapon of choice is the HDR Global wheel. In fact the HDR tools are becoming my fave "go-to" tools for balancing my projects. When running and gunning, I mostly set my camera to 5600k unless I remember to change things when in the field. Back in front of my computer, then, I worry about the consequences in post production. I also question my decision to fall down the rabbit hole of colour correction and grading.
You might want to learn about how camera sensors capture light in the analog domain before being digitized. And you also want to learn about the how the human perception works. Otherwise you won't understand at all.
@@shueibdahir I understand how a camera captures light, and its limitations compared to what my eye can see which is why I shoot with a non-linear log colour space to capture as much information as possible within those limitations.
@@frankinblackpool Well the HDR wheels and the linear gain work In the same way, manipulating brightness linearly instead of logarithmically. I like shooting linear raw for the exact reason that it perfectly replicates the light values of the scene which in very awesome when grading for HDR delivery (Rec.2020 ST2084). Once you shoot linear, you'll have a hard time going back. Log compresses the highlights and the deep shadows too much for my liking
I've heard that linear gain behaves like global wheel in HDR pallete. Is it true? Can I balance shots using this HDR wheels, because I really like this photometric control over exposition, and changing WB in the same tool would be more comfortable.
Would you put this linear color balance node upstream or downstream of your exposure node? (Or if parallel, top or bottom node input?) I know Resolve processes temp/tint upstream of exposure/contrast in its node-internal order-of-operations, so I'm tempted to put my balance node upstream of exposure for that reason alone. But is there a reason why I should put it downstream instead?
Thank you Cullen, im using input CST node and output CST node to use davinci wide gamut. And im using that Lift-Gamma-Gain method to get constant white-balance. But not choosing Linear on Node Gamma. Is it bad or not ?
Ahhh i am confused, i watched a video of waquas qasi the famous color grade(i dont know if i got his name right) and he said he always starts with temp, tint and contrast🙈
That is awesome, I have a grudge with cameras WB (most generic cams), dull and cold sunny days or cloudy days with an iron oxide patina, it's crazy maybe I got spoiled by the film era with fixed WB.

Which ones are those videos? Thanks!

Learning to use Gamma, offset, and following the vector scope to help me out is what really did it for me. Helped drastically
The Gamma, linear and gain way of balancing wb has blown my mind. Just tried it out... this will be the way I do it going forward. Thank you.
I learn a lot from watching ur videoes, thank you for making them constantly and providing us valuable infromation!
you pack so much info that I need to watch your vids at 2x, thank you so much!
Awesome video Cullen! I wish BMD would update some of these tools. It's been years since some of them are in that imperfect state....

You lost me at "Spectral Locus" 😂 Just kidding, this was super helpful!

Great video, Cullen!
Great stuff! Love this viewpoint

Amazing tutorial. Thank you! But how to I steal your perfect posture though?
So good!
just when i wanted to start working Jess from Gilmore Girls uploaded
You are my RUclips bestie !!! just saying...
Why don't you use one of those white, grey colour board things, or use the dropper to click on a white object in the material?
How about using printer lights?
Awesome video Cullen, thank you for sharing
my question is irrelevant but, could you tell us when is the grade school? i remember first it was Friday and then turns out to Monday.
and these days i always check community note and channel but no news about grade school :(
Kind of off topic but Cullen is really professional with his voice and presentation. How do you not botch some lines here and there?
My man here never heard of editing
Great video, as always! Just curious - when working on a linear node, why is Gain the go-to tool, and not the other wheels?
He just did a video on that! Check out his last few videos on this, it’s great!
Just rewatched it.
His question is warranted.

How to use something like "Crhomatic adaptation" in Premiere

U da best!
What about just HDR offset since it s a color managed tool?
Why gain and not offset?
i always assumed because u dont want to introduce too much color to your shadows and make them muddy
