Here are the test prints I managed to keep, some of them got lost with the business of everyone pulling their prints out and drying them... Most of them are here. They show how I tested the Contrast and exposure times. I would do two test orints of each image... one test on gradient 0 and one test on gradient 5 at 10 second intervals. This would allow me to see what exposure and contrast values to use or to even combine in split grade printing.
I test printed for every image and contact sheet.
