Hello everyone, After shooting digital for several years I became discontent and wanted to start playing with film. I've been successfully developing my own Fuji Presto 400 using Fujifilm Microfine developer. Today I tried developing my first roll of Rollei IR400 film. I read in a post on another site that you do NOT have to presoak the film to remove any anti-halation layer (something I have zero experience with.) I decided to give it a try with what I had so I developed a roll with my Fuji Microfine developer. I did 9 minutes 30 second at 20 degrees (Celcius, I'm in Japan). When I poured the developer out to my surprise it was a clear, deep, yellow (sorry for the gross analogy, but it looked like urine.) It was pretty clear beforehand and had never changed when developing Preso B&W film. My question is what caused this? Is there a layer that should have been washed away with a pre-soak? Is this some kind of indication that I exhausted the chemicals with this roll? Any info. is much appreciated! Also, I live in small-town Japan and getting any kind of variety of chemistry is a challenge, so I'm just sticking with the Fuji stuff I've been able to get for now. BTW - the film is hanging and drying now and it looks like it developed decently. Thanks!
