Q&A
-
Can I combine selections made with different Selection tools?
-
Yes. Make a selection with one of the tools, switch tools, and then press the Shift key before you add to your selection. As long as you hold down the Shift key (making a tiny plus sign visible next to the tool), you can add to your selection as many times as you want.
-
How can I deselect part of a selection?
-
The easiest way to do this is to press Option (Mac) or Alt (Windows) key with the Selection tool active. You will see a small minus symbol next to the Selection tool. Select the part of the selection to deselect, and it is removed from the selection and added back to the picture.
-
Can I use the marquee to draw a shape and then fill it?
-
Yes, and that's exactly how to do it. With the selection active, use the Paint Bucket to pour a color into the selected shape(s).

Exercise
Most pictures can be improved by careful cropping. Try this experiment. Cut two L-shaped pieces from a sheet of paper or cardboard, as shown in Figure 3.19.
Figure 3.19 How to use a cropping frame.
Use these pieces as a cropping frame and look at your snapshots or at pictures in a magazine to see how different cropping affects the picture. Try finding long, narrow compositions, square ones, and rectangles.
