What are the rules here? Can I use other images to add to the source image? Do I have to document an added image in regard to source, license, etc? Can I use other software than PS? I use only open source applications like Gimp, Darktable, and Inkscape.
Welcome to Grepless Coffey. You can use any creative commons images and add them to the source image to make your manipulation. It helps with voting if you at least make a picture of all the sources you have used. Here is an example from the last contest. https://imgur.com/a/DtFMXP6
You may use any graphic software you like. It is not a requirement to only use PS.
