This has happened never before . My first time developing Ilford HP5 35 mm in Pyrocat HD, semi-stand, and the white dots on film . Problem with bubbles or what? I pre washed the film for 5 min and then avout 3-5 min agitation and then stand about 20 min, agitation for 2-3 min and stand for 25. All together 50 min which has been great for 6x6 film. Here can be seen the dots. Naturally black dots on print . Well, I messed up with this more and it "got light"... But let's not talk about that Question is, what did I do wrong? I have developed a lot of films the same way and this problem never occured.
