Re: [photo-3d] UFO's in my slide show

Rough guess: your slides are mounted in glass...

The phenomenon you describe (assuming I'm right!) is caused by condensation 
pn the glass. It's actually very difficult to get film completely dry before 
mounting in glass, so I now mount in RBT plastic (non glassed) mounts and 
project in RBT projectors (autofocus) which has completely solved the problem 
(but doesn't help you! :-)   )

 Practicing with the projector this evening on some of my slides and a 
 weird phenomenon occurred. I'd put in a slide and it would look fine, 
 then after 5 or 10 seconds an Unidentified Fogging Object appeared. 
 It was, as far as I could tell, always from the left lens, and it 
 looked like moisture in an oval shape around the center of the image, 
 probably covering 80% when it appeared and shrinking to 25% before I 
 pulled it out in a panic. At first I thought the slides were 
 overheating, but that didn't seem to be the case and it looked more 
 like moisture.
 
 Any idea what's going on? Could it be moisture in the projector? Why 
 wouldn't it show at the very beginning? Suggestions appreciated... 
 Don't answer off-list because I won't see it till I get back home.
 
 Thanks,
