Re: Color meter reference light sources

I used to carry a Minolta Colormeter III with a flash receptor constantly during the film era. I sold it when I went digital, but noonday sun should run around 5000-5500 degrees K, though a warm sunset might drop to a surprising 3200 K. A deep shadow only illuminated by pure blue sky can rocket up to an amazing 20,000 K!

A speedlight might run around 6000 K, but varies on how yellowed the plastic lens has become with use. An old fashioned tungsten bulb might run 2600-3000 K. A unfiltered stage spotlight around 3200-3400 K.

Honestly, with digital I don't worry about it anymore.
