Close to this topic: to quickly index a slide collection, do the following simple setup and procedure: I've set up a 2Mp camera to record and file my 10,000 or so slides. I put the camera on a tripod immediately behind and above the projector, which is aimed at a piece of white matte-surfaced Formica about 24" square. The image is about 12" square and very bright about 60" away. I zoom the lens out so that the projection will fit either vertically or horizontally and leave it on autofocus and autoexposure, color corrected for incandescent. I just load the slides and shoot, occasionally checking focus on the grain. I do it at night and put black velvet on the table to minimize ambient light on the screen. The camera automatically records the date and sequence number, which I afterwards write on the slides so I can go back for a scan if needed. I put sticky notes on each stack to keep in order. Some nice background music and a cold drink helps. Why? Michael said it's a waste of time, and it is if you're looking for scanner quality. But when it takes (me) over 8 minutes to find, dust, load, scan, remove, mark and re-store just 4 slides (2 min avg) on my scanner, it will take me years. Instead I can leave the slides in their storage boxes to project, dust if they need it, and shoot away -- it's a LOT quicker. I've done 365 slides in one evening, about 3 hours (30 sec avg, or 4x faster). It's still a long project but no longer hopeless. This is only a prescan for seeing which ones are useful to take the time to scan. I mark the slides that have been shot with a light color spot and those that are scanned later with a dark color over the light-color spot. For starters, I can batch-correct bad slides for color-shift and fade, and optionally I'll crop out the black border to get a better look (3:2 35mm slide format vs. 4:3 digital) by zooming. I mark the slide boxes against a computer file directory where the image files were put. Also, the HD is not loaded with slide files that probably will never be used anyway. Getting a close, zoomed look at these has been a revelation for me. Some are about 55 years old. Yes, I know it takes two processes instead of one and I considered that, but I'd rather prescan and index than do every single slide. I can quickly organize the slide images into directories and galleries and slide shows to decide what's next. And again, I'm not saying this is a replacement for scanning, but it continues to be very useful for me. It may be for others, and perhaps others have already done this. Comments are always welcome. --- Don Dement ========= Michael Healy wrote: >This is the method to which I resorted initially, because I was impatient >and had no scanner.
