In this video I take you through the steps to step-test a cyanotype fabric and digital negative. The step-test in this video took place in March at noon with clear skies. The fabric was exposed with the following times in minutes: 5, 7, 9, 11, 13, 15, and 17. This is Part I. In Part II we will look at the results of the step test and two other exposures: a seven minute exposure and a four minute exposure.
