I've been working on the problem of archiving scientific (and forensic) images for a long time. I've completed (several times) the digitizing of a huge archive of professional and personal images. Being in a philosophical mood, and feeling a little "apotheosized", I thought I'd lay down some commandments for anyone who is interested. If you're not interested, why are you still reading this? Like several better known systems of ethical rules, the first commandment is I. Do no harm. Always keep the original slide/image. If the pessimists are right, and digital is ephemeral, then the original may have survived well enough to be re-scanned. If the realists are right and entropy will engulf everything, it couldn't hurt. II. Copy the image. What you want for archival work is to reproduce the surviving image as close to the real, existing slide as you can. If the film is magenta-hued, the archival copy should be also. If it’s grainy, so also, etc. You are, of course allowed to do non-intrusive cleaning of any dust on the image. Turn off as much of the “dust reduction” and the like as you can in your copying workflow. At the best, dust reduction will be neutral, but at its worst, you are achieving “dust free” by blurring the image. Dust cleaning can be done automatically or manually later to copies, not to the "archival" image from the scanner. Ditto for color correction and other such processes. This is, of course, in reference to evidential images. If you are scanning images of the family puppy (Hi, Begheera), turn on all the automatic crap you can find if you can stand the results. III. Scan once, scan high. The reason I have "completed" my scans more than once, is because I tried to save time and effort by making only small copies of the originals. If the images are archival, START by scanning as high resolution and quality as you can. It will save time in the long run, believe me. Subtotal I emphasize that I'm talking about evidential imagery, not your personal snapshots. The problem I'm addressing is that of people not approaching digitization of older images in a systematic way, mixing up different levels of the work flow. The key here is to keep "interpretation" of the image separate from the "archiving" of the original image as it came from the camera and medium. That's probably enough for this post. I can surely run to at least seven more commandments. but this is enough for argument.
