Creating Layer Masks
A Layer Mask is a way to mask areas of a layer so that only certain areas of the layer’s image display. This layer works only with bitmap images, so vector images cannot be used to create a masking area. You learn about vector image shapes in Chapter 10. You use the Brush and the Eraser tools to define your mask areas. You do this based on colors:
- Paint white on all areas you want to be visible.
- Paint black on all areas you want to be hidden.
- Use shades of gray for areas to apply a transparency.
A quick way to choose white is to use the Web hexadecimal equivalent of #FFFFFF or the black hexadecimal equivalent of #000000.
- Open a photo that has multiple layers in the Photo Editor.
- Click the Expert mode.
- Click to select the layer that you want to attach a mask.
Click the Add a Mask button.
A layer mask is created for the selected layer. To define the mask area, make sure the Mask thumbnail is selected.
Click the Color Picker foreground color.
- Click a color of black, white, or a shade of gray. You can click in the Hexadecimal box and type a hexadecimal equivalent.
Click OK to close the Color Picker.
- Click the Brush tool from the toolbox.
- Set your Brush settings. (This topic is covered in Chapter 10.)
- Click and drag to paint your mask area.
- Repeat steps 5–11 to continue to develop your mask.
