Why not change to Lab mode then copy the L channel to a new document make your edits then copy that and paste back into the L channel of your original image?

somehow I was not able to do that.

It's like LAB locks you out.

Do you have a way to do that?

I copies the image to new file. Converted to LAB there. Went to channels, copied the luminosity.

But then when I tried pasting anywhere it won't let and same in reverse, it won't accept backward.

Would be nice to try
