    <pre> Hello Mark,

    While it is practical to do, it depends entirely on the volume of material you have. We've had success with shooting maps and drawings onto medium format film and then have the film drum scanned. The results have been fairly good, picking up the relatively small type associated with maps. However, it is a costly option ($25-$30 per image) and not suitable to large volumes.

    Some of the newer prosumer digital cameras are in the 3 megapixel range that may be adequate for digital reproduction in conjunction with a copystand. The key here is good lighting -- a two point diffuse lighting system that provides a steady light would be ideal instead of relying on a digital camera's flash.

    One alternative would be to shoot to slide. The current batch of slide scanners is relatively inexpensive ($2500 - $3000) compared to a few years ago and yield fairly high resolution images. Nikon or Minolta would be good places to check in this regard.

    Tim
