I scanned at 4000 dpi in 64-bit RGBI mode, set the infrared cleaning to medium intensity (I didn't use any other post-processing), and saved the file as an uncompressed 48-bit TIFF. My computer is a PIII 800, with 768 MB The scan itself took 55 seconds. Post-processing and saving the file to disk took 2:10, for a total scan time of 3:05. The file was 111.5 MB. Opening it in PS7 took 7 seconds. The big gotcha with working on files this size is the RAM that PS consumes if you do a lot of manipulations in 16 bit format. The history palette can chew up a ton of memory, and things start to bog down. 768KB is workable, but my next machine will have at least 2 GB of RAM.
