After postponing several times, finally I jumped head first into a project that will likely take up on-and-off several years: the scanning of my pre-digital era slides (about 13 thousand...). After reading the reviews of various available scanners on filmscanner.info I settled down on a Reflecta ProScan 10T which seemed to offer the best price/quality combination. The scanner is advertised as 10k dpi maximum resolution, however in reality tests show that there is no perceivable resolution difference between a 10k and a 5k scan. 5k is still more than enough for the purpose, it produces 7125x4750 pixel images (30 megapixels) with a resolution showing the individual grains in the original film, all detail is captured. For colour fidelity I use SilverFast rather than the OEM software, it produces far better results, especially when it comes to restoring faded colours. The most impressive feature is the infrared scratch/dust removal that physically identifies the faults on the surface of the film rather than using a software based method which can eliminate some photo details. Below an example showing a very scratched slide from my 1981 Sudan trip (the tomb of the Khalifa in Omdurman) showing the result with and without scratch removal, plus a detail of the maximum resolution scan. Scan + processing takes about 3.5 minutes per slide, but after the 2 minute scan one can pre-scan the next one and select the settings while processing completes. I found that I can do six slides (the number that fits the strip film holder) in about 30 minutes, including the time to remove from frames, place into feeder and scan. If anyone plans to do the same, I'm happy to share my experiences in more detail.
