Yes, technically any set of consecutive lookup tables can be combined into a single LUT.
However, it's often easier to stack them and just makes sense. Plus, 16-bit color makes it technically possible.
Let's say that you're working with a color-sensitive piece in a color-correct pipeline. First adjustment layer should be to bring your pantone color card to look right. Then, the next adjustment right after that would be your overall grading pass, e.g "cold" or "vintage". Then, the next pass could be to "get those skin tones a little pinker". Much easier than working on a single global correction layer.
- dperfect 11y agoI agree with that. 16-bit color helps a lot (but doesn't completely eliminate the risk of throwing away data), and the approach you mentioned (correction vs grading) is a valid exception to my point - though if you're doing that, you likely understand what you're doing and the potential gotchas. My point was more targeted toward the numerous tutorials I see where people use many such adjustment layers without real purpose other than to "play around" with the color, turning the image into a posterized mess (especially by stretching things too far one way, then essentially negating that adjustment with something else).
