So don't leave slides laying around, even in pages, where the sun can get at 'em. However, how often to you project them? And how long are they in the machine, 15 seconds? I've never shown the same show more than a few times, for a combined two or three minutes total projection time. You will notice the quality of dupes, but most audiences will not, since they've never seen the show before. Good quality dupes can be quite pleasing, but if you're only showing that show a few times, why not use the originals? Ektachromes are far more resilient to fading than Kodachrome. Indeed, all commercial slide presentations intended to be shown often are produced on Ektachrome or other E6s. These are usually business presentations with commercial graphs and charts, etc. However, go to any camera club meeting, or any presentation by a serious or professional photographer from another disipline, and you will always see originals in the projector. And these guys guard those carousels with their life. The birders and scenery crowd, for example, don't even speak the word dupe in normal conversation. The model crowd (pretty ladies, not trains) are used to tossing slides around like trading cards, since they shoot so many frames per setup, but even they will only project originals. I guess it's a matter of pride. ....Mike -> SPORRS: 'Serious Photographers Of Railroad Related Subjects' -> Web Site: http://www.anet-stl.com/acphotog/sporrs/ -> Message © 1998 SPORRS® - All Rights Reserved
