As a designer and occasional photographer, I found it helpful to carry around a little "cheat sheet" with these items when out in the field shooting. This reference is useful for amateurs and the occasional photographer wanting to learn more.

Many of these are applicable to SLR cameras and video camera settings as well

Resolution (for digital and video cameras)

F-Stop - Aperture (f-stop f/22 – f/1.4)

Shutter Speed

ISO – Film speed (100-1000 speed)
