Technology of Photography
I have just recieved a free Encyclopaedia Britannica subscription because i run a blog, and since this blog is photography based, i though i would test it out with a link to the The Technology of Photography.
The way it works is if you are someone who publishes to the web on a regular occation, like a blogger, you can get a free subscription and post links on your site. Very cool stuff. the link above is quite lengthy and very informitive, but, say you just want info on SLR cameras thats posible too! Thanks Encycolpaedia Britannica!
