    Well, I am pleased to report that today's effort appears to be a complete success. Everything appears to have come out exactly as intended. Yesssss......

    Out of curiosity, is "one shot" developer truly one shot? If I wanted, for example, to do two rolls back to back, could I reuse it?

    I wouldn't reuse it. You will get consistent results with one shot.
    my 2 cents...Terry

    Congratulations!

    And as posted above, one shot developer shouldn't be reused. There are developers and development regimes that are designed to permit re-use, but using them is either more complex (involving replenishment, or extensions of time) or unusual process methods or results (two bath developers like Diafine).

    Trust me - you will appreciate the simplicity of one shot until you are more in the swing of things again.

    Ironically the only time a one shot developer could probably be reused is when the entire roll is blank ;-)
    Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.

    Using the developer consumes it pretty significantly, and leaves behind products of development and things from the film. So you can't re-use a developer that was not designed to be re-used, sorry. Your second roll is likely to come out significantly thinner (underdeveloped).

    As to your "more what?" question: increasing any one of concentration, temperature or time will increase the amount of development action to your film, which in turn increases the contrast. Under-developed film has too-low contrast and (often) no shadow detail, whereas over-developed film has too-high contrast and will start to lose highlight details. If the contrast is too extreme in either direction, the negative will not be able to be printed cleanly on photographic paper; it might be rescuable via scanning but if the contrast is so whacked that it doesn't print well, it's likely to have faults in addition to extreme contrast that are much harder or impossible to correct. A bit of contrast variation is no problem and there are frameworks (see below) for deliberately varying contrast during development in order to optimise your images for the contrast in the scene.

    The definition of "too much" or "too little" contrast depends on your paper. Modern variable contrast papers will successfully print a wide range of contrasts, which is nice because we get significant variation in contrast from the scene lighting and from differences (or mistakes) in development technique. If you want to know more, google up "Zone System" and "BTZS" and buy a copy of Way Beyond Monochrome; it is an excellent reference on B&W technique. There's a FAQ in my signature that I suspect might help you too.

    One shot is one shot, In some cases in a pinch with some developers folks can run a second roll by developing for a longer time, as long as the second roll is developed within a few moments of the first one. (as one shot developers will not keep after mixing to working strength in most cases)

    Best idea is to only use them one shot, and accept that you are throwing away some left over power. That is the Buffer than ensures that you have enough power to accomplish your mission.

    Absolute best way is to replenish. But first lets get this guy one successful roll and then he can start having densiometer and btzs arguments with the rest of us.
