    PyrocatHD 400TX Jobo

    I'd like to develop 120 400tx in a Jobo at 75* F with Pyrocat HD 1 + 1 + 100. Does anyone have a starting point for development time testing?

    How will you be printing?

    And is that TRI- 320?

    Hi Sandy,

    With a diffusion enlarger on graded SG paper. It's 400tx and not the 320.

    Is this a jobo ATL? I have a time at work that has worked well for me. I'll send it along tomorrow morning.

    Peter,

    Sorry, but I have never tested or used TRI-X 400.

    Hi Sandy,

    What would you suggest for the 320? (I do have some 4x5 320 Tri-x that I might use down the road.)

    Peter

    For printing with TXP-320 on a graded #2 silver paper I would suggest about 11 minutes at 72F with Pyrocat-HD 1:1:100, with rotary processing.

    Just to report, I tried 9 minutes at 75*F with the Jobo on the slowest rotational settings. The negatives look pretty good. Perhaps they're a little on the contrasty side, but it's hard to tell without printing. (I only have a BW transmission densitometer.) I'll probably try 8 minutes next time if the lighting is at all contrasty. There's quite a bit of stain. (My BW densitometer say fb + fog is .33) Recently, I've been using Pyrocat with Maco Infrared (both the old stuff and the prototype) and Rollei infrared. Neither of these films showed much stain.
