Masks are a wonderful tool for creating collages to showcase your photos. The techniques in this tutorial demonstrate how to use a variety of shapes as photo cut-outs to make collage templates. Each shape is placed on its own layer and made into a mask. Once your masks are ready, it’s a snap to insert photos into each one. The benefit of using masks when you make collage templates is that you are not limited to standard shapes for the photo cut-outs – you can use any kind of unusual shape you wish, and the masking will prevent your photos from overlapping each other or straying outside the boundaries of the photo cut-outs.
