The next time you burn through a roll film, also make an equivalent image of the same subjects using a non-film camera. While your roll is out being developed, study your non-film images. When the prints from the film roll arrive, then you can make a comparison. If you find that you really liked some of your non-film images, but their film based equivalents just didn't cut it, I'm sure the cause will reveal itself at that time. The purpose of the comparison, of course, is to demonstrate that memory is not always as accurate as we imagine to be. ;-)
