Today I tried to mix my own chemicals for bw reversal and tried it to process a roll of Rollei Retro 100 (the one that it is supposed to be identical to Agfa APX100 -and it seems to be). I tried a variation of the Ilford reversal recipe using rodinal 1+10 instead of their paper developer and a potassium permanganate bleach. Until now I had used the Foma reversal kit which seems to be very similar with very good results both on Fomapan R and Agfa scala. Well, the film came almost transparent, the emulsion was extremely soft and it was like it was about to melt. The leader of the film was crystal clear as it should be but the unexposed parts (between frames and above the sprockets) were clear too but covered with the soft emulsion instead of being black. I first noticed that something was wrong at the light exposure step when I realised that the film wasn't milk white coloured as it should but similar with a normal processed negative. Still, there was some image on it (I cannot recall if it was negative of positive, negative probably). After I fixed the film (with my normal tetenal thiosulfate fixer) it was almost transparent with some very weak positive picture on the soft emulsion. A total disaster! I suspect that the 7gr sodium thiosulfate crystals I added in the 600ml first developer (rodinal 1+10) were too much or that the bleaching time was too long (5min) but still I cannot figure out what went wrong. Any ideas?
