There are no layers for 'sharpening' and 'shadows and highlights' adjustments in PS CC. So when I sharpen an image if I want to cancel it later I can't do it. It is same for 'shadows and highlights' adjustment as well. So, is there a way to keep such adjustments and delete them if I want later? One way might be dublicating the background layer and doing the sharpening by choosing this layer and renaming it as 'sharpening' and if I don't want it, I can delete it later. I can do the same thing for 'shadows and highlights' adjustments too. But this is the solution I have found out on my own. Is this the right way or is there any other more reasonable way?
