Hi David,

    Re. your comment about needing a high resolution digital camera to
    match the results from an SLR, this is only part of the story.
    Whatever equipment you use to photograph the items, the results will
    only be as good as the device used to print them. A 3 Mega pixel or,
    in some case even a 2 Mega pixel digital camera will produce and
    image of 2048 x 1638 pixels which is usually quite sufficient for
    publication. However, if you try to print it out on an average
    inkjet printer to a large size and using the 'standard' settings of
    maybe only 72 dots per inch, the picture will look indistinct. In
    effect, you can directly compare the number of pixels in the picture
    to the 'grain' of film and, for a high quality print, you need a
    printer that can print a large number of 'dots per inch', a graphics
    program that will, if necessary, interpolate the original image to
    'fill in' the gaps in the image caused by stretching the available
    number of pixels to match the number of dots, and a high quality
    paper which will not allow the ink to smear and run like blotting
    paper. 

Best Wishes,
Ian
