One of the trickiest moments when processing cyanotypes is the drying process. An unevenly dried exposure will produce unwanted and distracting purple streaks as the residual salts gather in puddles. As such, when I'm producing a group of cyanotypes, my studio often looks like a laundry room. The most effective way to dry them I've found is by hanging them with a fan gently moving the air around the space. The second issue is the integrity of the paper can become compromised during the development process - this can be dealt with by applying the chemical to any substrate, but most of my exposures have been produced on 40lb bond - a paper that tends to disintegrate when not handled with extreme care.
