Establish perfect exposure times easily with the Stouffer step guide. There are many different ways for exposing plates. There are an abundance of different exposure systems and processing techniques. The one constant is the step tablet. Use the step tablet as a benchmark for all exposures to achieve accuracy and repeatability.
