Mixing real paint, real paper and Photoshop has always worked for me. Photoshop allows me to fix things that are not quite right with my prints once they have dried. I can digitally erase or add things precisely where I want. What control I can have after making a fun mess with paint!
Each digital paper is created with SEVERAL layers in Photoshop. Various blending modes are used and sometimes I also adjust the colors a bit.
Here are some digital papers I made from that Gelli Print in my last post.
All of these digital papers are available for sale at photoDUDS
