    Developer: Rodinal 1+50 (6ml + 300ml).

    I invert the Jobo(35mm) tank 3 times every 5 minutes during 15 minutes of development. I get negs that print straight on MCP 310 paper.

    Stop & Fix and vigorous rinse(10 times at-least) Finally Adoflo.

    15 minutes, that sounds like quite a long time. The published times I've seen range from 7-10 minutes for N development. What EI are you shooting at and what temperature is your developer? MCP 310 is the paper that I have just switched to.

    Temps: 20°C before pouring the developer. I never measured the temps after development.

    EI: Box Speed, but I had K2(Yellow filter) so I set my incident meter ISO=50 and measured EV 14(It was sunny on top of the mountain). I had everything on that negative to print.

    Yes, the meter was facing the camera. :-)

    Unfortunate I do not own a scanner, I will try to give it to the lab to get it scanned during weekend.

    I am no expert in processing film but I follow this http://www.apug.org/forums/forum216/...-negative.html also I never tested with any other agitation methods so I cannot comment about other times.

    Ok, I have been using around 8-9 minutes with good results. I expose my film at EI 80. I am surprised that 15 minutes doesn't block up your highlights or lead to too much constrast.

    I presume you may agitate on every minute. I personally do 3 gentle inversions once in five minutes and on 15th minute I pour it down.

    In that article author has explained the advantages of this method, further the comments that followed gives even more information.

    More over the developing scheme is just a part of the entire system since you may have to consider the enlarger type, paper and so on.

    I think there's a big difference whether you agitate every 30 seconds or every 5 minutes.
    I like my film stirred, not shaken.

    Yeah, I misread that. It makes sense now. I am doing 10 seconds, every minute. Usually with just one full inversion each minute.

    I'm trying to picture taking 10 seconds to invert the tank. 5 seconds on the way down, then 5 seconds on the way up? Would be like slow-motion, yes?

    No I agitate other directions for that 10 seconds, only inverting it fully once during that time. But I figure now that this was a mistake as far as to the uneven development. Like I said, I was afraid of too much contrast.

    If you you are unformfortable with the Foma film and the pictures you hope to take on your upcoming trip will be irreplacable may I suggest a first tier film such as Ilford FP4+. Regretably you get what you pay for.
