Where was this when I was in college?

Well, crap. I spent a semester in introductory telecommunications production to learn stuff like this, and here it is on the internet for free (sure, this is a static camera and not digital video - but the basics are the same, I assure you):


Digital Cameras: User's Guide:
Adjusting Your Digital Camera's Exposure

Oh well. Happy to have it now that I am trying to remember what the F-Stop numbers mean (not what it does, just what it means -- darn you! No, I haven't forgotten everything I learned in school! ...well, maybe FinalCut).
