    Hello! You will need the print drums. An 8x10 drum can do one 8x10 or four 4x5. You will need the rubber spacer to separate each row of two 4x5 (or make one - there is an article on the site that...

    Re: Film for Astrophotography

    TMax 400 is the best B&W film at present, though it looses 2 1/2 to 3 stops for long exposure. Hypered Tech Pan was the best, but I doubt that you'll find it.
    Several color films are good,...

    Re: Unicolor Drum ... How much soup ?

    Hello! With TMax RS, I used 270cc for the 11x14 drum and two 8x10 sheets of TMax. For the 8x10 drum and 4 sheets of 4x5, I used 135cc. Both worked well. With some experimentation, I'm sure I could...

    Re: Paper negative vs film

    Hello! You can pick up a Unicolor roller for $15 or so on E-Bay. An 11x14 print drum will go for $10 and will do two sheets of 8x10 at a time. No temperature control, unlike the Jobo. However, for...

    Hello! This sounds like the catechol developers give increased contrast in the highlights because of self-masking, like an inverted 'S' instead of the classic 'S' log exposure curve? Best regards.
