Making multiple adjustment layers to one part of photo
I make a duplicate layer; highlight one part of the image to edit; create an adjustment layer with mask for Levels; make adjustments; then how do I do edits for Brightness/Contrast and Hue/Saturation to that same highlighted area? If I go the duplicate layer again and go to adjustment layer for Hue/Saturation, the mask is for the whole image; same thing if I click on the Levels layer mask and then adjustment layer for Hue and Saturation, I just get a mask for the whole image. It seems like it should be so simple to make multiple adjustments to just one part of the imge.
