    Developing MACO IR 820 / 400 Professional

    Hi

    I have ordered this film along with some of you here at APUG.
    Anyone up for discussing the development of the film?
    I will (of course) soup at least one roll in Rodinal, but what will YOU do?

    Rodinal of course!

    I recently developed some Maco 820c Aura (5x4) in Rodinal 1+25, 9 min at 20C (per Massive Dev Chart). Here is a neg scan: http://not.contaxg.com/document.php?id=7420&full=1
    Shot through a Heliopan 715 filter, metered at effective EI of 5.

    I started with Rodinal 1+50 and went on to Pyrocat-HD. Both work well. Much more important in my experience is the right filter and the right exposure. An R29 will give you dark skies, nice wood effect aso. without much halation and with more open shaddows. With a very dark filter you need very long exposures (starting point 3-6 ASA), get lots of halation in the highlights and will loose the shaddows. You may like either one better depending on your expectations but the lighter filter is much easier to work with.

    I will probably try and develop it in D76 stock.

    Pete, This is a beautiful image and I would like to ask how you came to an EI of 5?

    I tried the Maco 820/120 (the plain film, not Aura) with my Rolleiflex 3.5F with the original Rollei IR filter (equivalent to 695?). I rated it 4 ASA and used D76 1+1 13:00 at 20 deg. with continous movement (Jobo ATL). This gave good negs for an diffusion enlarger. Metering was with an unfiltered incident meter (Gossen Lunasix 3)

    One thing to know is that the meter isn't measuring the IR light. I had excellent results with one scene (landscape with blue skies and about 50% white clouds), but the next scene on the same film (clear blue sky, no clouds) gave about 1 - 1.5 stop underexposure. So bracket interesting shots. BTW., I had no problems with standard Jobo 25xx-drums.

    Thank you Bruce. The Maco tech sheet is available at Retro Photographic:
    http://www.retrophotographic.com/PDF...0c_AURA_UK.pdf
    It recommends an EI of 3-6, so for a very sunny day (as that was) I tried 5. It's the first time I've used the Maco 820, so it was a lucky guess really. Later in the day there was less direct sun and I switched to EI 4. Those negs also seem to have worked well. With the 715 filter, you can hold it up to your eye and, after an adjustment period, see where the IR reflectivity is high. It helps with composition as well as giving a feeling for how much IR light is around.

    As an aside, I shoot Maco at an EI of 1/2. It has to do with developer (PMK) and how much shadow detail one wants.

    Technology is not a panacea. It alone will not move your art forward. Only through developing your own aesthetic - free from the tools that create it - can you find new dimension to your work.

    I'll be using a Heliopan IR 695, since it's one of the few available in 39mm (I'll be using a Bessa L with 21mm Skopar lens). I may also try it with a lee filter in a 35mm back on my Bronica, with 40mm wide-angle lens for some 24x56mm "panoramas".

    The IR820's I've used I have developed in Pyrocat-HD. For 35mm I'll try Beutler's.
