Adding and subtracting from selections

Is it possible to make a selection of this semi-complex shape  in only 3 selections? Of course the answer is yes.
Ok if you’ve given up, or want to check your answer, here’s how its done.

Step 1

Using the elliptical marquee tool make a selection around the outside circle. If you hold down the spacebar as you create the selection, you move the entire selection. Release the spacebar but not the mouse to continue drawing the selection.
Release the mouse. You will now see the marching ants as you have selected the outside circle.

Step 2

Let’s cut a circular selection out of the center to select just the ring.
With the elliptical marquee tool still selected, hold down Alt (Option). You will see a little minus sign by your cursor. You are about to subtract from your selected oval. Drag in the middle until you selected the inside circle.
Release the mouse and now you have selected the ring. Congratulations, you just created a complex selection.

Step 3

What about the rectangular shape? Do you think that we should subtract or add a selection here? You got it, we need to add some pixels to our selection.
Choose the rectangular marquee tool.
Hold down the shift key. You will now see a plus sign by your cursor. This means that you will add to the selection
Drag the cursor over the rectangular area.
Release the mouse. You now have selected the shape using a combination of tools. You have also used the add, and subtract from selection options. Powerful allies when making selections.

Step 4

Ok what are you going to do with this selection? The most common reason people will select is to remove the background. Here is the best and easiest way of doing just that.
With your shape still selected. (If you accidentally turned off the selection, choose Select>reselect.)
Choose the move tool. (V key)
Press Ctrl-J(c-J)  to copy the selection to a new layer.
Click the eye icon in the layers palette next to Background

The background is now hidden and you see the checkerboard pattern. This lets you know that the shape is now floating on a transparent background. You can add this to a collage, save it for a publication, export it as a transparent image for the web or what ever you want to do with it.
