[edit] Fast Shutter Speeds
Reciprocity failure also exists at the other end of the spectrum -- when shutter speeds are faster than 1/1000 of a second. In that case the aperature has to be opened wider to compensate for the short exposure time.
Reciprocity failure is supposedly useful in astrophotography. Can someone elucidate?
[edit] EV=5 Example
Shouldn't the exposure time be 4.5 seconds in the example? I realize that it is nice to round off, but in this case, the round-off error is almost 10% of the exposure time. I'll change it in a few days, unless there are objections. (neffk <neffk ta ieee tod org> 9 April 2006)
