Any photographers out there? I may have a method for using a digital camera as a light meter. White paper at 70 lux reflects 61% of the incident light. Set your camera at ISO100 and take a picture of white paper in the incident light level to be measured with your existing lighting in kitchen, family room, whatever. Convert your shutter speed and f stop of that photo to an exposure value. http://en.wikipedia.org/wiki/Exposure_value Convert your exposure value to lux http://www.intl-lighttech.com/support/calculator Multiply by 1/0.61. Upgrade or downgrade your lighting (watts, lumens) to suit. http://www.personal.psu.edu/users/a/s/asp5045/roomcalclivingroom.htm Will this work?
