Editing Selections
Software : Photoshop CS2
Level : Beginner

Concept: Once you select any part of the image you may need to add or subtract the selection. We use Shift key to add and Alt key to subtract any selection. The same rule is applied to other selection tool also.

1. Open Photoshop. Open Image to work with rectangular marquee tool.

2. Select Rectangular Marquee Tool from toolbox. Drag on the image. You will get animated selection border. It indicated the area selected by the tool.

3. Press Shift and drag another rectangle overlapping some part of the previous one. Now release shift key. You will get the addition of the two selections.

4. If you press Alt key and drag second selection, the overlapping part will get subtracted from the first one.

5. You can try similar technique using Elliptical Marquee Tool also.
