Photoshop Palette: Adjustment

ADJUSTMENTS: 
Adjustment layers give you the ability to apply an effect to a group of layers in Photoshop, and then you can edit that effect later, while preserving the original layers.

Photshop history palette stores and displays

The History palette stores and displays each action performed allowing you jump to any recent stage of the image alteration. The alterations should be created during the current working session; after saving or closing the document the History palette clears all the contents. Each time you apply a change to an image, the new state of that image is added to the palette. The History palette can store up to 20 stages. However, you can always go back to the first stage, for example opening the document. It is important to know that once you click on any of the previous stages, all the changes that were made after it will be lost.
