Layers
Layer Visibility
Sometimes, you want to just work on a certain layer, or you want to turn off a layer so that your image isn't so cluttered. That is what is great about using layers, because it is so easy to move things around, temporarily turn things off, and rearranging the stacking order of elements on your image!
Next to each layer in your layers palette, you will see a little checkbox. Clicking on that checkbox will turn that layer's visibility ON or OFF. In this case, the layer have both been turned on, so they are both showing:
Remember: You can only work on a layer that is selected in the layers palette. In the example above, Layer 0 is selected. I need to go click on the background copy layer in order to work on that layer.
