Layers and Masks
Importing a depth map
Another way of incorporating a depth map is to create a suitable bitmap image
separately (or borrow one from somewhere else) and then paste it via the
separately (or borrow one from somewhere else) and then paste it via the
Clipboard to an existing PhotoPlus depth map.
Using masks
Masking in a program like PhotoPlus is a bit more complicated than applying
masking tape to the screen! But fundamentally the concept is the same: you can
masking tape to the screen! But fundamentally the concept is the same: you can
hide certain parts of an image—in this case by rendering them transparent,
hence invisible. To do that, you create a mask on a non-Background layer (the
Background layer doesn't support transparency).

By changing the grayscale values on the mask (using the paint tools and other
devices), you can impose corresponding changes in the opacity of the
underlying layer's pixels (values stored as the layer's alpha channel) . For

example, by applying a gradient "blacking out" across the mask, you gradually

Besides the creative possibilities, ranging from vignetting to multi-layer montage
to gradient-fill masking (see example above) and beyond, a great feature of
working on a mask is that it is "temporary." If you don't like the way things are
going, you can abandon your changes and start over without ever having
affected the actual pixels on the layer!
Each non-Background layer can have one mask at any given time. (The

Each non-Background layer can have one mask at any given time. (The
Background layer can’t have one because it doesn’t support transparency.) Mask
