So I made some cyanotype prints for the first time.
So much fun !!! :D
However I seemed to be getting some artifacts in my highlights
See around the ship:
Original to compare:
So after exposing in the sun and starting to wash the print I noticed the artifact. It looked similar to what you see in the photo, but it was a pale violet color. As the print dried, most of it faded, then some turned yellow (kinda like the unexposed chems) then later turned into the blue colored artifact you see in the photo now.
What is causing this artifact, and how do I fix it?
