I've done 3'x4' cyanotypes on plywood, using eight 4' long UV florescent
bulbs mounted in a box for a light source, and waxed and/or oiled xerox
prints as the negative. Kinko's Copy (a national chain of reproduction
shops) has machines that can produce a 3' wide copy, and these, doubled,
are what I use for the negative. Exposure times run about 12 hours. I made
a 4' square rinsing tray to wash the prints out in the front yard. If the
image quality sucked (and it usually did), I'd simply recoat the surface
with a clear transparent acrylic medium that had volcanic ash added to it,
recoat, and layer a new exposure on top of the previous one. I've used both
the standard and dichromated formulas. I did most of my MFA show this way.

Almost all of the steps and troubleshooting were sorted out with the help
of this list. Cyanotype is very forgiving and puts up well with ham-fisted
measures such as the ones I've described. I'm at a standstill as I've
become even more Alt. than expected, having been hired as a news
photographer shooting video for a T.V. station in San Jose.
