With this setup involving a home-made slide/camera/flash holding jig, a computer with wi-fi, an iPod touch, a iPod/iPhone app called DSLRRemote and a computer program called DLSRRemote Server... I can copy slides to RAW format as fast as I can plop them in the holder, and take them out again. I copied 600 slides while watching Aliens on TV. The copies are sharper than from my transparency scanner, and the files are at least 16-bit (being RAW files), and 10 megapixels. The camera is tethered to the computer with a USB cable, and doesn't write files to its internal memory card, so the batteries last forever. The flash is set to 1/32 of full power, so its batteries too last for a long time. I do this in relative darkness so dust on the slide isn't illuminated from the front (which would make dust spots show up as white). Instead dust is backlit which makes it show up as dark spots which are easier to hide or ignore. A guard in front of the flash prevents light from illuminating the whole room when it fires. The process is a lot faster than in the video when I have two hands to do the work. see the rig at www.flickr.com
