    First time rotary processing B/W film : Success..

    After last weeks processing failure, doing a semi-stand development of Fomapan 100, this morning I tried rotary processing 6 sheets in my 2520 drum... The negs came out beautifully, lots of density in the highlights, nice deep shadows...

    I did a bit of googling and found a post on APUG outlining a standard development for fomapan 100 in Rodinal 1+50 of 8:30 @ 20C. My tap water here was 25 so I went with 5:13 @ 25C with rotary development in my home made roller setup (soon to be a water tempered rotary processing system)

    I will hopefully post results from the scans later tonight or tomorrow but at this stage I'm happy to say that I feel like I've found something that works well for me with Fomapan.. The only thing I might do is next time drop it back just a little to get a little less strength in the highlights but I will wait until I scan the film before I make any serious judgements on that.

    Very good. Congratulations.

    Note that Rodinal is a compensating developer when used with minimal agitation, per the instructions.

    When using it in a rotary processing system that compensation effect is lost.

    The result is that for identically-exposed negatives, the rotary one will have slightly greater highlight density.

    As long as you like the looks of the negatives, that's what matters.

    If you believe you can, or you believe you can't... you're right.

    FYI,
    If your tap water is coming out too hot, freeze a few water bottles(filled 1/2way, and capped of course) and dunk one of them in your mixed chemistry(or the water before you mix it up) to cool it down. Have 3-4 of these "chiller bombs"(as I call them) ready before you get started processing, so you can temper you chemicals to your desired temperature.

    Just a suggestion recommended to me a few years ago, and I've found it to be really helpful in warmer climates.

    cheers,
    Dan

    Looks almost perfect to me, beautiful picture... Do you still have some shadow detail in the darkest parts of the negative?

    +1 on the comments by Leigh. I would also give Xtol a try. Rodinal is a special purpose developer that articulates grains. You will have less than perfect scan results if you ever decide to do scanning...

    Thanks guys.

    The negative shows substantially more shadow detail. This has been adjusted to how I want the details portrayed.

    I have son xtol here but haven't mixed it yet.
