Photoshop: Opacity stops not working in gradient map

Anyone have any idea?, although inside the gradient editor window the gradient bar does show transparency in the correct tonality areas when opacity reduce, it doesn't apply to the photo, and being completely ignored. Can anyone please help?

i think that's because gradient maps don't support or have a need for transparency. Normal gradients do, which is why the controls are there.

And they really do need to redo the interface for both... there's simply no reason why we should have to go 3 windows deep to change a color.

That is correct, the Gradient Map adjustment ignores opacity in the gradient (because how you apply transparency for that adjustment gets confusing really quickly).

Maybe I'm missing something here so let me share more information and why would I need the opacity stops to work, look at the attached example, I want to apply the gradient map colours only to the highlights and shadows and to fade the colours all the way to a complete transparent (no colour gradient) mid tones.

Is there a way to create a dynamic luminosity mask so I could add/subtract tonal values from the mask on the fly? (similar to if the slider would do what I mentioned)?

btw - why the adjustment don't work this way? isn't it a desirable functionality or it contradict somehow the basic functionality of the gradient map adjustment? it does make allot of sense for it to work as appears on the gradient in the gradient editor window.

No, there is no way to create a dynamic mask like that.

And, again, how to apply the transparency from the gradient is confusing at best. (especially when combined with existing transparency on the layer)

Thank you Chris,
I still hope that the opacity stop in gradient map adjustment would work similarly as the opacity stop in the normal gradient adjustment - in terms of the desirable functionality of the opacity stop - it is identical.

The gradient part is simple. What is not simple is how that applies as an adjustment to your image.

but the same applies as an adjustment to the image with the gradient adjustment
