    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!

    Since no one has volunteered, I suppose I can give you my thoughts on the subject. It just won't be of any help.

    I once developed Kodak movie stock film in C-41, but I don't remember if the developer turned yellow, and I had to remove the anti-halation backing manually.

    Hmm, you're right. Your comment isn't of any help.

    strange, i comment about this and my post has disappeared.
    anyway, it is very commone for various combinations of film and developer to change color .

    i have seen orange, green , purple among other shades.

    Does this mean the developer is still OK to use, or should it be disposed of?

    The strange thing is I looked at it again and it turned from yellow back to mostly clear!

    I don't want to use it if it's compromised now, but at the same time, in small-town Japan, with my limited ability to buy developer, I want to get as much use as possible out of what I have.

    -Will

    how do your negative look? that is the real guide line.

    if they are fine, then i wouldn't worry. it is just a trait of the combination your using.

    My negatives look OK. They are a little flat, but I'm not surprised since I only made an educated guess at time and temperature since I had no data for Rollei IR400 in Fuji Microfine. This was just a test roll for me.

    My concern is ... is my chemistry OK to use for more film or did something happen to it?

    Do a test strip- the cut off ends of undeveloped film do eell- if they come out clear, you are OK- but developer is cheap and I sould not take a chance of ruining a greeat shot- pour it out and mix some more.
