� Overview Operation Conclusion
Overview salvage usable (i.e., better than nothing) images at EV 3 and 4. Outside daylight at noon is about EV 16, and a well lit indoor office runs about EV 9. In a small room with faded white walls and an eight-foot ceiling, lit by two incandescent hundred-watt lamps near opposite walls you get about EV 4 -- for example, my spare room turned office.
rough rule of thumb, because the acceptability of the pictures you take in dark situations varies greatly with the type of light (diffused, collimated, point source) and the amount of ambient "fill" light, as well as the color, brightness, and reflectivity of the objects in the picture.
Phlash is one attempt at a solution to the low light problem that many makes of cell phones share. The idea is good -- turn on some light right before you snap the picture. However, for the Treo, Phlash's implementation suffers from some problems, some of which are immutable functions of physics and photons.
