I'm looking for method to scan over 6 million images for a huge digital archive (conversion from all kinds of sizes to one dpi/resolution). Obviously the man hours involved make this a big of a big undertaking and I'm wondering if there is such a thing as an industrial scale automated scanner i.e you stack up a pile of photos on a machine and it scans them to disk until it's done, only needing to be reloaded from time to time.
Has anyone ever encountered such a thing?
To answer questions which have arisen: no paper will be used this is photo to file only. Resolution: 600dpi max, colour scans. Nothing too huge, I'm guessing there wouldnt be much more than $20-50k available for the system.
