  7. Layers Palette • Most images are composed of multiple layers. • The Layers palette displays all layers within an open image. • You can use the Layers palette to create, delete, merge, copy, and reposition layers. • The effect created by using layers is similar to what you see when you look at a stack of clear plastic sheets. • Hide or show a layer by clicking the Eye icon.

  8. Layers • They are images or effects overlaid on top of one another. • The standard kind of layer is called simply "Layer" in most programs. It contains just a picture which can be superimposed on another one. • A layer can have a certain transparency/opacity and a number of other properties.

  9. History Palette • Each action you perform during an editing session is recorded and made visible in the History palette. • The History palette tracks recent changes made within an image. • You can remove actions from the History palette.
