B. Information on equivalent exposures and the implications on depth of field are found at
http://scphoto.com/Notes/Day_11/sld007.htm
C. Math wizards may want to peruse more information on equivalent exposures and the formal definition of exposure value at http://en.wikipedia.org/wiki/Exposure_value
D. Check out another basic explanation http://www.photonhead.com/exposure/exposure.php
and be sure to try their cool Simcams.
E. Since so many of you are using digital point and shoot type cameras we need investigate
