This is in response to Ann Graham (mailto:fi98@jove.acs.unt.edu) who requested information on slide scanners.We (the slide library at IDRC) have been using the Nikon LS-3510 AF 35mm film scanner (12 bit) for the past year. I realize that better, faster are currently available, but the Nikon has proven satisfactory for our purposes.
We use medium resolution because of both scan time and disk space constraints: i.e. a scanning resolution of 1058 dpi (3 pitch), which results in adequate quality and a very manageable file size of approximately 150-200 k per slide (using JPG compression). However, with this setting, it takes approximately 4 minutes to process 1 slide (including scan time, crop time, and save to disk time). As each slide is processed individually, and the scanner ties up the computer system during scan time, this might pose a problem if a high outout and/or fast results are required.
The maximum scanning resolution this scanner can handle is 3175 dpi (or 1 pitch). We have not tested the time it takes to process a slide at this setting.
Some other information regarding this scanner:
Price: $11 150 Can. SCSI Interface with 1742 card for this scanner: $590 Can. Weight: approx. 13 lbs. Dim.: 11.3 " x 14.41" x 5.86 "
