Ran across the mention of "chromazone metering" while reading reviews of the Nikon D100. Anyone out there had any experience with this method? Exactly what is this system? Is it practical? Does it work, or is it just another "gimmick"?
Go to http://photonaturalist.com/chromazone - to see what I am talking about. Is it worth buying this product (color cards, instructional video, etc.)? Any opinions from someone who has ACTUALLY USED THIS SYSTEM?
