    I'm going to try and test this film and wondered if my methods sounded okay.

    I have 15 exposed sheets of 6.5cm x9cm and three of them are of the same subject with the same settings. These three will be my control of sorts. I plan on running 3 batches with each batch having one of the control. Each batch will develop for a different time.

    I was told to start with 7 minutes so I plan on doing one for 6.5 min, one for 7 min and one for 7.5 min. I figure with the three controls I can compare them and see what I like.

    Remember, all this is very new to me so please tell me if there's a better way to do this. I don't have a darkroom and I'll be doing all this in a Jobo 3006. None of the exposures contain images that can't be reshot and I think of them as "playing around" images.

    Thanks,

    Alan.

    How do you intend to print these negs? Gelatin silver through and enlarger? Alt process? Also, what concentration of A:B:water are you planning to use? I agree with Jay regarding spacing out your processing times more.

    Good questions.

    15cc from small bottle
    30cc from large bottle
    1000cc water

    5 sheets of film at a time.

    Since my darkroom is a long way off I'll be printing cyanotypes and VDB. I know this film is small but using the camera is just so much fun :smile: I also have a 5x7 that seems much more appropriate for contact printing.

    I'll start with 7min and try the other times as suggested. Thanks guys!

    I souped the negs last night and started with 7min. Turned out ok I think. Some problems included mixing up the film and putting all three of the "control" negs in the first batch then only having enought hypo to only do one more batch.

    They're in the critique gallery now if you'd like to comment. Thanks again for the hand holding :smile: I'm having so much fun!

    I just popped over an looked at your posts, very nice.

    The tones are very attractive and they look plenty sharp. You have a very distinguished model; he fits the lighting and look perfectly.

    Just for the sake of argument, I would enlist his aid again and redo the shots. I would use the same lighting but this time do your three development time tests, instead of just the one.

    I agree with 5, 7, 9 as a better spread to determine change. And remember to MARK THE NEGATIVES so you know which is which, nip a corner or have a card with a number at the very edge when you take the picture. It's very frustrating to have a half a dozen negatives and no idea what was what, or so I hear, never having actually made that mistake myself!!! At least not that anyone can prove!
