I just returned from the School for Scanning 2007 in Minneapolis and was bombarded with a ton of information during the three days. One of the most interesting breakout sessions was with Franziska Frey from the Rochester Institute of Technology. In addition to discussing the changes in photography practice in recent times, Frey also discussed the imaging challenges that arise when digitization programs are confronted with an increasing amount of born digital materials.
This issue has started to come up here at UNLV, with questions directed to me asking what resolution something should be scanned at so that a donor can deposit a digital copy of their materials in Special Collections. Our Campus Photo Services staff have noted a drastic drop in darkroom processing requests from campus, and nationwide there are fewer new photographers learning these traditional developing skills. Now that film is no longer being as widely manufactured, and photographic paper and chemicals are starting to disappear this kind of question will only come up more often.
