    I develop Acros in Rodinal, usually 1:50, rather than D-76. The high-end results are about the same with either.

    Rodinal is a compensating developer, which gives greater highlight definition and control.
    It wants very little agitation. It doesn't work right with rotary processing, nor for high-ASA films (400 and above).

    Rodinal is ideal for small-volume users since the concentrate keeps indefinitely, even in partially-used bottles.
    People have reported using concentrate over 50 years old that still performed like new product.
    The working solution has a short life, a few hours. It should be mixed right before use (allowing the temperature to stabilize).

    BTW, due to some trademark bull, Rodinal is no longer available under that name.
    It's now known as R09 and one or two other names.

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

    So Rodinal is for tray developing then? I've been thinking about ways to turn one of the bathrooms into a darkroom.I'm starting to think its doable. At least for the short term. Every time I ask a question I find out that I know even less than I thought that I did.

    Yes. You can use it for tray development. I have done so on numerous occasions.

    Process the film emulsion down.
    Limit your first efforts to perhaps two or four sheets at a time. I can do six or eight at once.
    Slide the bottom sheet out at an angle (about 45).
    I usually work lengthwise (portait mode), pulling the sheets out rearward.
    Lay it flat on the surface of the developer and push down gently.
    Repeat until you've gone through the whole stack, then let the film sit for 30 seconds. Repeat.

    One point regarding Rodinal at high dilutions (1:50 or 1:100)...
    You need 10ml of concentrate for every four sheets of 4x5 film, regardless of the dilution.
    A 500ml bottle will do 200 sheets of 4x5 film.
