What method is used to create the 3D effect, dual image or blue/red shift?

Some home scanners come with slide and negative attachments. I tried it once but each slide took forever and, when I looked at how many I wanted to do, I decided the nether world would freeze over before I finished.

I finally scanned in my 30-yr old slides a couple years ago by projecting them onto a whiteboard (actually a white foamboard) then photographing them. The slides were taken with an instamatic 110 and so were quite small. The results were not competition quality but that was to be expected considering the condition of the slides and the quality of my screen. And just like old snapshots, they're still memories.

What was unexpected was that my underexposed slides showed more detail in the camera image than on the screen. Because my camera was set on Av the exposure time lengthened and captured more detail than I thought existed. This suggests that you could do an exposure bracket of shots for each and run them through HDR software to improve the overall image.

I'm sure there are people around who can scan them in for you if you have the money. Stokeley at Kings can probably give you a name or two. Otherwise you can probably still find a home scanner that will do the job.
