One Candlepower

- It would be hard to imagine a world without electric lights. Today our homes and work places are well lit. In the 1800's and earlier night was often without light and when it was provided it was a flame like this single candle. The now outdated term of candlepower was use to describe how much light was emitted from any artificial source. The term candlepower has been replaced by Candela which defines a single candle at 1/683 of a watt. Canon G11, 1/500 sec @ f/2.8, ISO 800 in macro mode, 3 stops underexposed.
