How to Use Layers: The Basics


Start by making the Layer palette visible. To do this go to Window/ Layers

A window that looks something like this should pop up, if it wasn't already there:


Each of the items there (consisting of an icon and a name on a row) is a separate layer. Only one layer can be selected at a time, and all modifications that you make in Photoshop only happen to the layer you are on (unless the modification is an adjustment layer itself).


Each layer has two boxes to the left that indicate if the layer is visible, selected, or linked. By clicking on the "eye" icon, you can hide the layer. Reclicking on that box will make the layer visible again. Holding down the "option" key while clicking on a layer's "eyecon" will hide all other layers. Repeating that step will make all others visible again.

All layers have a cumulative effect upon each other starting wiht the layer that is on top. The top layer supercedes all others, and the bottom ones show through where the top ones aren'y opaque. You can adjust the opacity of each layer by selecting the opacity in the upper right-hand corner of the palette.

Layers can be dragged and dropped so one is above another. This excludes the background, which is locked, and cannot be moved unless it is redefined as a layer itself. This is done by double-clicking on it.
