I prepared the pictures on my pages http://www.nwjones.demon.co.uk/
by scanning prints. It is awkward particularly as like most butterfly
photographers I take slides. TO take prints I have tried a slide copier
whihc fits on the front of my camera and loaded the camera with print
film. The results are not always good as my local print shop is probably
better set up to deal with holiday snaps. I have also had individual prints
done from slides but this is expensive.

It is worth remembering that if you are going to use the images for
web pages that you do not require a high resolution image. Indeed if
you make the reolution higher than that of a computer screen it is too high
as the resolution is wasted and adds to the download time.
Another option is to use a video camera. The images can then be digitised
into the computer and single frames treated in the same way as those from a
I have been using this method to sample checkerspot wing patterns.
Traditional photography is simply to slow to sample large numbers of specimens.
Incidentally collecting the specmens is not an option when you are working
with the Quino and Bay Checkerspots which are both federally protected

may be reconceived, though its first material expression be destroyed; a
vanished harmony may yet again inspire the composer; but when the last
individual of a race of living things breathes no more another heaven and
another earth must pass before such a one can be again." William Beebe
