Many thanks for the comments about my article both here and in direct emails. Your interest in eBooks was reconfirmed, and I got good leads about sites that handle eBook sales online and outfits that offer POD services. I am currently reformatting the text for a different font and font size. I hope to have some news soon about publication of the book.

Excerpts from my book started appearing on Michael Reichmann's site today. Traditional publishers have not expressed any interest yet; in fact, none of them has seen more than the title and table of contents. I am now considering "Publish on demand" perhaps with Lulu.com or Authorhouse.com. That would produce an expensive paperback available on Amazon.com and elsewhere, and would permit me to purchase less expensive copies to distribute on my own. I could also sell eBooks at much lower rates.
In any event I expect a small audience for the book because it is really fairly high level science. I think a love of science is required as well as a scientific way of looking at the world. Besides that, there are equations, graphs, and tables. It does not tell anyone how to use their camera, but rather provides answers to questions such as: what does ISO sensitivity mean, what is the signal-to-noise ratio, what are color spaces, how does a lens coating work, what is a circular polarizer, etc. The information and the level are similar to that found in the Handbook of Photography and the FOCAL Encyclopedia of Photography, except of course my book is much more up to date. Keep tuned. I will let you know what happens.
