the easiest way to describe the photometer is by increasing the intensity of a light source, a light dependant resistor contained inside will lower the resistance...
high intensity - low resistance and high current low intensity - high resistance and low current
[edit] Photometers in photography
It is my understanding that photometers are quite regularly used in measuring ambient light levels of scenes intended to be photographed.
The main article could be improved if there were a paragraph on commercial grade photometers used in photography, and the shooting of cinema.
If modern photometers rely upon charge coupled devices (or CCDs), do they ever "burn out" by pointing at the sun? at campfires? at a lit match?198.177.27.18 (talk) 03:49, 26 May 2008 (UTC)
- That's covered at Light meter. I added a link there. Perhaps the two articles should be merged, though. It's not clear to me if there is a distinction between a photometer and a light meter.--Srleffler (talk) 05:00, 26 May 2008 (UTC)
