Making a Selection Larger or Smaller

It is often useful to create a compound selection from multiple areas of an image. All you have to do to automatically combine selections is press the shift Q key between individual selections.

You can also "subtract" a new selection from an existing one using the m (0) keyPressing (Mac: creates the intersected selection and you can use |ctrl|-Q-(T~ to invert it (i.e., select everything that was not included in the previous selection).

The combined selection described above can also be further combined with selections made using the other tools described below.

You can give a selection a hard or a soft edge and you can round its corners using the options listed in the options bar. We will use the Lasso tool as an example.

You will use selection tools so often that you will automatically learn the necessary keystrokes. The tables in the margin on this page are designed to help you, too. The QQ F ^ icons in the tool bar have the same effects as the listed keystrokes.
