I finally succeeded in making a good negative for cyanotype with HP5+ today.
I processed it for 20 minutes at 85 degrees. I shot it at 3200 in my
pinhole camera. The subject was a test scene that I set up, with a gray
card, a piece of denim which measured two stops darker than the gray card
for zone III, and a white plastic chair which was zone VII. The denim
measured .31 and the chair 1.86. This is close enough for government work.
But again, if the contrast of the scene was low and development needed to be
expanded further, it would be difficult, I think, without simmering the film
on the stove or something for half an hour or so!
