RE: Mottling in lighter tones in cyanotype?

Cor, with cyanotype the correct exposure time is very sensitive to the
moisture level (both paper and working area) and the print-out is not easy
to interpret (especially for delicate highlights). So I opted to use bone
dry paper, ruling out the moisture parameter from the equation. Now, my
success rate is 2x higher than using non bone-dry paper.
