My old Pentax Spot meter started acting up while I was on my trip in July - the "high range" readings became erratic. When I got home, I cleaned the Hi/Lo range switch contacts and it seemed fine. The next time I went to use it, the high range was dead. I took it apart again and found numerous poor solder joints (which I repaired). I did some 4x5 copy shots for POP prints, overdeveloped 25% (as usual for POP) and they still came out thin (. . . scratches head . . .) ? ? ?
I don't have another meter (that I trust) and I don't even have a grey card.
Is there any way to check a spot meter without another meter or grey card (other than exposing a test print)?
Thanks . . .
