An updated issue of my technical article "Describing the 'strength' of visible light" has just been published on my technical information site, The Pumpkin. This is a link to its listing on the index page:
http://dougkerr.net/Pumpkin/index.htm#Strength_visble_light
The article clarifies the significance of, and difference between, such quantities as luminous intensity, illuminance, and luminance. No advanced mathematics is involved.
This information does not directly benefit most photographic technique, but is pertinent as background for those who get into such topics as exposure metering.
Best regards,
Doug
