Описание к видео Testing film. How i get four tests out of one sheet of film.

I re enact how I got four process strips tested from one sheet of 5x4 in one go. This was a good way to find out where you stand if you are experimenting with a stab in the dark combination of chemicals to film. My results from this test as shown in my previous video show the results of adding Potassium Hydroxide to PMK Pyro.
