This is how GIMP represents transparency. Now I'll hide the background layer and our three ovals are sitting on a checkerboard pattern. Shift click again to bring them all back. Now only the red layer is visible and all the others are hidden. And there's a shortcut for when you want to hide all the other layers except for one, just hold the shift key and click on the layers eyeball button. So I can click here to hide the red oval, click again to show it. You can control the visibility of each layer by clicking on the corresponding button with the eyeball. Now let's look at some of the other controls in the layers dialogue. So if I hold shift I can click anywhere, like on the blue oval, and drag to move the red layer. Notice in the move tool options under tool toggle that you can hold the shift key and click and drag to move the active layer regardless of where you click. I'll click and drag the blue oval again to move it back.
But when I release my mouse button, the red layer is selected again. The blue layer is automatically selected and I can drag to move the blue oval. So notice I still have the red layer selected and if I want to move the blue oval, I can just click and hold on it. You don't have to first select that layer. If you want to move items, you can take the move tool and then click anywhere in the image. So remember to click on a layer that you want to adjust first.
Notice how the layer is highlighted in the dialogue and even if the layers dialogue is closed, you can still tell which layer is active when you have certain tools like the move tool or the zoom tool because the layer name appears in the status area of the image window right down here. If I wanted to edit the red circle, I would first click on the red layer. In GIMP there can be only one selected layer at a time. In order to modify the contents of a layer, I first have to select or target that layer in the layers dialogue.
And then there are three layers each with a colored oval, yellow, blue and red. At the bottom of the stack there's a background layer and this layer has some special properties which we'll see as we go. So to get started let's take a look at our exercise file in the layers dialogue.

And in this movie we'll start our look at working with layers with the basic tasks of creating and managing them. In order to get the most out of using GIMP, you should become comfortable using the layers dialogue and the commands in the layers menu.
