Ok, this may be a naive question, but E-TTL measures reflected light
intensity - given the inverse square law, doesn't that amount to
distance information? Seems the problem most people are having,
though, is when *multiple" distances are involved. How is it possible
for Nikon's, or anybody's system, to make calcualtions based on
numerous fore, middle, and background targets?
