Hi I've been using the darkroom for some time now but up till now used the darkroom provided at my university. i just set up my own darkroom and today I made several prints from different negative, different rolls of film. I followed all of the appropriate steps to my knowledge and when I initially viewed test strips and prints in the light they were fine, however when I finished up and began looking at my prints outside after a few minutes the edges began to look purple in colour then I noticed the prints beginning to get dark patched on the surface as though they were exposing to the light. Im almost certain the prints were fixed properly does anyone have any suggestions as to what happened? I've googled and am drawing a blank.
