The problem at the moment is that affordable CCD cameras are only 640 x
480 pixels (or slightly more on the Kodak). It's the kind of difference
between video cards 800x 600 is better than 640 x 480 and neither have
the same resoloution as a camera. For gel photos we use a 640 x 480 CCD
for lab books but for literature we use 35mm film. 640 x 480 captured
using a frame grabber card prints quite nicely on cheap 600dpi lasers ie
HP Laserjet 5L or Panasonic GDI KX6300. 

For say fluorescent colour images I don't think you can beat the
cheapness of the digital cameras but who needs coloured agarose gels?
