One would think. Is there a > problem with your Minolta shutter? Could there be a light leak in you > gaffer tape tube. Or is there light reflecting off the inside of the tube. > As a matter of fact I had just come back to the computer to report that I think I've figured it out. After I wrote and sent the sentence about no logical function between exposure times and negative density, it occurred to me that that sounds like a shutter malfunction, because after all film does respond to light in a consistent fashion if the laws of physics are still in place. And after THAT I suddenly remembered that the reason that camera was replaced, many years ago, was because it had a bad shutter. Which just shows two things: (1) the laws of physics still rule, and (2) one doesn't do one's best thinking when racing a deadline. Thanks, Chris, for the thoughtful suggestions. Katharine
