It is the Affinity Photo program which I bought and downloaded to my computer. I started off with a free trial. I'm trying to use masks to change colors to certain things in a picture. When I was painting it stopped and I could not continue and had to start all over again. Yesterday, I tried to use a black and white mask and it showed a weird color and the places I painted and not all Black and White. I think this is a bad program and maybe I need to uninstall it and get another one. I'm very disappointed!!!!
