Hello,
As far as file format is concerned, we store everything as .tif
(uncompressed), the scanner produces tifs, and we convert all the files
captured on the Nikon camera from raw. This is for preservation purposes,
the minimum file size being 50mb. We do however store a separate low
resolution jpeg archive for use on web, powerpoint, reference etc. That
may change as we implement a new Image Management System which will create
jpgs on the fly from our Tif archive.
While we are on the subject I wondered if I could digress slightly and ask
what equipment people use to digitise glass plates and large / medium
format transparencies. Typically we scan these on a flat bed scanner, but
have recently been discussing a camera set up with a light box. Has
anyone come across any problems concerning the latter and would you say
that it is more time efficient using camera instead of scanner?
Many thanks, I look forward to your replies.
