Sandy,
I assume you are scanning in 16 bit grayscale, but below is a table for
scanning 5x7 at various resolutions. It would be pretty close to a Photoshop
file. I assume you will scan at some native (non interpolated) resolution of the
scanner. Pixels column would equal the size of an 8 bit grayscale file.
All numbers are in megabytes.
Scan Res Pixels B&W (16) RGB RGB
Res 16 Bit 8 bit 16 bit
300 3.2 6.3 9.45 18.9
600 12.6 25.2 37.8 75.6
1200 50.4 100.8 151.2 302.4
1800 113.4 226.8 340.2 680.4
3600 453.6 907.2 1360.8 2721.6
Hope this helps.
Mark
