RE: Cyanotypes

Sorry,

I didn't mean to turn this into the cyanotype forum,
but it's been so dead lately that I didn't think I'd
be stealing bandwidth, and I knew some of the pinhole
people would know about this. Kate mentioned 45
minutes as an exposure time. I was already surprised
because of the "overexposure" effect (not fogging) of
my first attempts with a 4-minute exposure. I have
subsequently done one more successfully with only a
two-minute exposure. Hmmmm. And again, my main
surprise was that the blue kept getting darker for a
day or two after exposure. Sounds like a difficult
process to control. I guess it's time to hit the
books. I was just experimenting with a little kit made
for kids called "The Sunlight Print." Maybe it's
designed to be very sensitive so the kids don't have
to wait? Anyway, thanks for the thoughts...

Colin
