Based upon the responses from this group, I have a hunch the film I have is not exposed. But I think it is worth a run to the photo lab. I know they will be able to tell by looking at the cannisters. If you all didn't think I was crazy, I guess the lab won't laugh too much. <grin> If the cannisters are unused film, I will just toss them. I'm sure they are too old to waste the time taking pictures. Thanks for all your suggestions. Phyllis in NJ
