Pour out fixer into jug. Wash according to Ilford method. For sheet film in the Paterson Orbital it is still the Ilford method but with the four of each agitation just continued for 10 seconds, then 20 seconds, then one minute, then another minute and two more minutes after that. Then a stand in water with 0.5ml of Mirasol in 500ml of water for one minute. Very slight agitation, more a roll round with the lid off so I can see that I make no bubbles, about every 15 seconds. Then carry tray and film through to drying cabinet. Clip up the film by a corner, still in the water. Lift it out smoothly and hang it up to drip dry. After five minutes blot the great big drop off each lower corner with a tightly folded tissue so that only the very edge of the corner actually gets touched. Then dry it.

    Thanks Andrew, I have a fresh supply of HD and MC but will contact them next. SHipping the pyrocat from the USA has become a little bit expansive.

    Re: Obsidian Aqua, catechol staining developer

    First time I ever photographed in a Canadian rain forest. I don't normally shoot trees. Just down the road from my house. Semi-stand in Obsidian Aqua. 45 minutes, three agitation cycles, one minute at the start, a third of the way in, and two thirds in, 10 seconds each. BTZS tube, filled to the brim (1200ml total solution). 21C.
    It's quite sharp compared to my previous example. Same lens was used. I'll have to play around with dilution. I think a more dilute solution will end up looking more like the results that I can get with a very dilute pyrocat-hd. Looks like it could make a good compensating developer, too.
    Down to the darkroom to make some glop!

    FP4. But I believe the glow is due to back lighting.

    I'm sure it's just unique, must be perfectly centered between to hit both sides? Anyway it's great

    It's fairly centred, but I lost some of the sun when I went to make the exposure.
