16. In the Layers panel, click the Add Layer Mask button.
A layer mask is a map of areas that will be visible in the selected layer. The mask you
just created is a raster-based pixel mask, based on the active selection when you created
the mask. This is a non-destructive way to hide certain elements of a layer without
permanently deleting pixels; you can edit or disable the layer mask at any time.

The layer mask thumbnail
shows the masked
(hidden) areas in black.
As long as the mask is linked
to the layer, the mask will
move along with the layer.
You can click this icon to
unlink the layer from its mask.

On the masked layer, pixels outside Add Layer Mask button
the original selection are hidden.
