Photoshop: Ability to select curves mode selection (HSL Curve)

How about being able to choose the curves working mode? Like, adding a HSL curves adjustment layer?

In which application?

Please understand that curves work on the channels of the document, in a minimally destructive way. Doing a color conversion as part of the curves adjustment would be more destructive, and pretty misleading.

I think we can work around this by separating the image's color channels and the additional "channels" with a divider. If it's also only available in RGB, nobody will get their CMYK-separations affected.

A color space conversion is then only performed if you use curves on the special channels (and it's only available in RGB, so it won't matter).

Besides, nobody expects a luminosity-adjustment to only affect a single channel in a color image. There are a bunch of software out there (especially for video editing) that lets you adjust things like saturation curves already.

My suggestion is channels for Hue, Saturation and Luminosity (using the usual Photoshop recipie). Lab could perhaps be added as well (if nothing else just to get people to stop converting to Lab for no reason).

It could look like this:

I know for sure that Saturation curves would cut down the number of Adjustment layers in most of my files (a good thing for sure in 8-bit documents).

If the Photoshop team still thinks this would be confusing (to who? how?) then please add it as a new type of adjustment layer instead. Saturation curves would be the bee's knees.

Actually... If you are to leave Curves alone, you could completely overhaul "Hue/Saturation" instead as HSL-curves would cover the same functionality (but with a larger level of detail, and be more efficient for professionals).

Perhaps an option to click "Advanced" to roll out the curves-view if you are worried that it will confuse novice users.

Your suggestion doesn't change the destructive result at all. It might be better if you described what you were trying to accomplish instead of your imagined solution.

I'm just trying to adjust components like HSL using curves (an interface like "Curves", but doesn't have to be part of the Curves Adjustments we have today).

That's what other people here want as well I believe.

I do a lot of retouching and this level of control over e.g. saturation would be worth its weight in gold. The more I think about it, the more details that have to be adressed show up... If "amount/value" is on the Y axis, should we have hue, saturation or lightness on the X axis? All are useful in different scenarios, so perhaps a way to switch between the modes?. Hmm... Today in the Curves adjustment interface there is no room for this, so I think it would be best with a new adjustment altogether (or a replacement of hue/saturation as everything you can currently do with hue/saturation today would be covered by a new tool like this). Perhaps call it "grading"

I will put a bit more thought into it and create some mockups and image examples so it becomes easy to see what features I'd like to see and how they would be useful to users. An image can tell more than a thousand words, and if you like the idea it would be efficient for presenting the idea to whoever decides to look into it. ;)

Back up a step and describe what you are trying to accomplish, not the method you imagine might enable it. Don't mock it up, just describe what you are trying to do that you cannot easily do today.

Dear Adobe Gripe #8043

"Why do I have to switch an entire document to LAB mode and back (and flatten it in the process) if I just want to apply LAB curves to my current layer? And why are there no HSL curves?!"

Resurrecting and bumping this old thread because it's still a feature which almost all professional retouchers and colorists have been waiting for and need.

Also, fun that they now have it in places like AfterEffects and Premiere in the Lumetri filter/effect and it does exactly what we want. But yet not in Ps.


Ps: There the interface is also referred to as "Curves", something Chris Cox here was insisting we could not call it unless the thing being adjusted was the native color channels of the image. We should probably make a brand new post as then it's apparently a completely different topic, but I never got around to it.

yeah, another app has managed to add Lab and CMYK curves to RGB images, yet here we are still stuck in the 90s with only a single color model at a time.
I want all the curves!
