We’ve seen some work on diy digitizers before, but the one that [LP Rondeau] sent in is pretty sweet. It automates the process by advancing a slide projector carriage, blowing the slide clean with compressed air, and activating shutter release from a single controller. The images in this case have been shot in RAW (with a digital rebel ), and the setup allows immediate user review of the images – not to mention using the laptop for storage of all those huge images. The results of the shot and post processing are pretty good.
