This is just a thread I'm using to keep informative links on various aspects of photography...

Focal lengths and f-stop explained (http://www.paragon-press.com/lens/lenchart.htm)

A Tedious Explanation of the f-stop (http://www.uscoles.com/fstop.htm)
Wikipedia on f-number (http://en.wikipedia.org/wiki/F-number)

* when shooting by hand, make sure your shutter speed is at least the same (or faster) than your focal length. Eg: 1/100th @<hidden> 100mm, 1/200th @<hidden> 200mm, etc.

.. more to come.
