Create a mask by selecting a region
 
 
 

Choose a Paint > Select > Marquee tool and drag over a region or choose Paint > Select > Magic Wand and click a colored region.

You can create a mask by selecting a rectangular, elliptical, polygonal or lasso region, or by selecting a consistently colored area of an image layer (magic wand). You can also add to or subtract from the selection.

When you select a region, the selected region is unmasked and all other regions are masked. You can then convert the selected region into a mask from the Canvas Layer Editor.

To select a rectangular, elliptical, polygonal, or lasso region

  1. Select the image layer from which you want to select a region.

    See Select an image layer.

  2. Choose one of the following Paint > Select > Marquee tools:

    The cursor becomes a knife.

  3. In the Marquee Options section of the Paint Panel, set Mode to one of the following:
    • New—to create a new selection area
    • Add—to add to the selection area
    • Subtract—to subtract from the selection area
  4. Drag the stylus to create a rectangular, elliptical, polygonal, or lasso region.

    For the Marquee (polyline) tool, you must click, drag, and release the mouse to create each segment. Double-click to close the selection.

    TipYou can define your own hotkeys for the New, Add, and Subtract marquee operations. Choose Preferences > Interface > Hotkeys/Menu Editor and open the Special : Paint section.

To select a consistently colored area of an image layer

  1. Select the image layer from which you want to select a colored area.

    See Select an image layer.

  2. Choose Paint > Select > Magic Wand .

    NoteAlternately, you can set the Magic Wand Options before clicking the area or color of the image layer you want to fill.
    NoteIf you want to set the Tolerance before selecting another area, without affecting the area you’ve already selected (for example, to add to the selection), click Accept or choose Paint > Select > Magic Wand again.
