Mike, I think you ask a very interesting question.

Check out this page which I think is a nice, simple explanation of some of the basics regarding depth of field, without getting into equations and what not.

Things are so easy once you understand them, it's learning about them that's difficult ;)

To seekncritters: I teach photography 101, which is probably the toughest course in photography, hence the "illustrative" approach, once you grasp the concepts, things get so much easier after that... until you decide that you absolutely need to know how many photons per milliseconds can go through a bayer filter when they hits at a 68 degree angle.

I have to saying: A) Photography is so much easier when you enjoy it . :D

and B) There is life outside the laboratory. :?

Jean: Don't tell the kids in my lab that there is life outside the laboratory, I have a hard enough time keeping them working as it is.
