Comment: Re:just one f-stop? try 10-11 (Score 1) 107 107

I wouldn't say that most cameras have a "real" dynamic range of 10 f-stops (the upper and lower stops are usualy just a result of interpolation and thus cannot really be used in practice). Only top-notch ones have 10-11 f-stops (a average DSLR camera does not have more than 6 usable stops).

However, your point is clear, definitely much more than one.

Video cameras, however, have just one f-stop to work with at any one time, and so must make compromises

Just to name one example, the Red One has a wonderful dynamic range of 11.3 stops. http://en.wikipedia.org/wiki/Red_Digital_Cinema_Camera_Company
