You need a #3 dark green darkroom filter and ideally, a foot switch for it. Also the processing leading up to the inspection should be done under red light to preserve night vision. I would load the tank and develop to about 3/4 of the required time, then turn off the red light, open the tank, unroll the film a bit, emulsion side up and then turn on the green light with the foot switch. If the frames looked like dark rectangles, the developing was done. The green light can only be on for a few seconds (at a distance of about 2-1/2 feet), or the film will be fogged. It takes practice to get to know how to relate what the film looks like under the green light to how it ends up when fixed, but I think it's worth knowing. -- Alan Alan Magayne-Roshak, Senior Photographer University of Wisconsin-Milwaukee Photo Services (Retired) UPAA Photographer of the Year 1978 UPAA Master of the Profession 2014 amr3 at uwm.edu http://gallery.leica-users.org/v/Alan+Magayne-Roshak/ "All the technique in the world doesn't compensate for an inability to notice.
