    Hi. Another cyanotype question, which may apply to other processes as
well. I have been using the sun to expose my cyanotypes. When there are no
clouds, the exposure takes about three minutes, and I get about eight steps
on the step tablet. But, if it's cloudy, the exposure may take seven to
eight minutes, and I get more steps! Has anyone else observed this
phenomenon?
