PhotoMasque makes it possible to create advanced effects of contour and
transparency on your images by using preset masks. It's also possible to
create personalized masks. The images used in the masks are all in
grayscale. White is the color of transparency and levels of gray represent
opacity. The darker the gray, the more opaque will be the color applied.
PhotoMasque comes with several base masks, use them to inspire you to
create your own masks.
