R,G,B all open at once ?! Whaaaaa - request :)

[PhilipB]

Simple idea. I use all three curves regularly to achieve precise color matching, think luminosity on a Mcbeth chart grey patches.

Since we know (see below) that working in prophoto means that changes to one channel curve (say R) will result in an unintended change in another channel measured value for a given point (say green value on a locked color picker).

RGB curves - Why does adjusting the G curve also result in a change in R and B channels?

Cripes, can’t find it. Well, here goes again… Firstly, there are two essential bits of metadata that should follow an image from its capture all the way into any depiction: 1) the color primaries and whitepoint that represent its color space, and 2) the tone curve that took the data from its original linearly related values to something else. There are folks that’ll debate #2, but since all we have to do this with are ICC profiles, I’ll let my assertion hold… Now, when an image is captured …

Can we please have the R,G, &B curves all open at once? Much like tone curve 1 & 2 in the exposure tab. Please give us 1,2,&3 in the RGB curves section.

Thank you kindly !

You mean like this?

@PhilipB

tone curve 1 & 2 in the exposure tab.

That would be great also!

But really my preference would be to have 3 seperate tone curves similar to curve 1 & 2 in the exposure tab. But having both options would be the cat’s pajamas !
