Most of the time you can't actually see the leaks, even in the dark. Experiment: Take two identical photographs. 1st shot roll the film in and out immediately. 2nd shot don't advance the film and keep it in the light for 5-10 minutes. Every folder I ever had leaked except for ones with brand new bellows. chris At 02:31 PM 7/7/2005, you wrote: >No, a Color Skopar should not be giving you those results.
