Here is a selection of links I have collected and that I have found very informative about a number of subjects related to microscopes and their use.
It is an ongoing effort and I would like anyone to send me links that they think should be added to the collection.

MUST READ : Digital Imaging (Nikon UK). A really great resource, including Power Point slides from the course they offer. Even without the lecture material everyone interested in digital imaging should spend a lot of time on this site. It will provide the whole community a great reference for digital imaging discussions.

Charles' use of modest microscope equipment to get consistently top quality results should tell us all something about the process of photography.

Much of his work is on http://www.amateurmicroscopy.net/ Eye-Opening Images Highlight Nikon’s Microscopy Photo Awards By Salvatore Salamone wrote for Bio-It World points out a 6.25x enlargement one this years Nikon Small World Contest. Krebs' fly was one of a kind image that out stood out from the 19 other winning images an 10 honorable mentions that look more like abstract art than nature.

This is a particularly interesting area for me with a broad background
in agriculture as well. I host his web pages because he is one of the
foremost experimenters in home-made microscopy and has a broad
experience in both photomicroscopy and photomacrography. He is very
prolific in his work with microscopes, making do with affordable
solutions and getting professional results in his home shop. I am a bit
behind in keeping his web page up to date. It only covers his work in
microscopy and not any of his very good work in metallurgy. As a framer
I used some of the products he developed and they were some of the best
on the market. Agriculture is a very difficult market because the
costs are so high and the margins so thin throughout the industry. It
is not like most fields where throwing more money at the problem will
get results that are marketable. Anything that you make must make the
sure money right off the bat. In addition to all the scientific
work Ted is a master machinist as well. He has built many of the
machine tools he uses including an excellent lathe. He is presently
working on scanning light photomacrography system "Constructing

Ted is a consulting metallurgist and prolific author that has spent most of his life working for heavy industry. He manufactures precision microscope parts and a camera adapter available through McCrone & Associates and produces outstanding work modifying and building microscopes and image particular in dispersion staining.
