I have put the first draft of an article on view camera geometry at
http://www.math.northwestern.edu/~le...s/pages/vc.pdf

I should emphasize that this is a mathematics article and assumes some background in subjects like projective geometry. If you have neither the interest nor the background in such things, you should most definitely NOT look at it.

When I have finished it, I plan to write a much less technical article which describes the important facts without the detailed mathematical arguments.

As I said, it is a first draft. I haven't yet done the diagrams; one difficult section and some appendices are yet to be written. I'm not sure it is yet readable by anyone, but It is remotely possible someone will look at it and find some blooper or suggest some important issue I've missed. If you do, please let me know. I will keep updating it as I produce further drafts.
