    Hello everyone!

    I have a small question regarding slide mounts. Just recently I discovered that the reason for white/grey GEPE mounts is that the white one is to be seated towards the light, thus reflecting some part of the light and heat away from the slide.

    Well... just a while ago after a pause of a year I mounted a second batch of slides. However, during the projection I noticed that I had mounted them wrong way. While projecting this mistake was corrected easily with flipping the mount. Now, however, I wonder: should I open each one of those slides (about 80) and flip them around in the mount or does this really have any effect on the life expectancy of my slides? I don't project my slides in large spaces with very powerful projectors nor do I even look at them that often -- but would like to have them in good condition in the decades to come.

    Worth the effort?

    If projecting for a short time I wouldn't worry about it. If they are heating up and popping I would.
