[QUOTE="pforsell, post: 618579, member: 7240"] With all due respect and with most friendly kindness: that quoted sentence is so wrong that it's not easy to put it right. Nikon exposure meters have been tuned since time immemorial in such a way, that the spot metered value is 2.7EV below saturation. It still is true with D5. The meter is actually tuned to 12.8 % reflection, exactly as the Kodak grey card packaging tells. One counter example to the "... only be used when you have exactly an 18% grey ..." is like this: spot meter off the brightest highlights you want to preserve, set +2.7 EV exposure correction, and you're golden. When you want white snow instead of grey, white wedding gown instead of gray, black tuxedo instead of gray and so forth, use spot metering and set appropriate EC. The spot meter is the most useful metering mode. One can set the tones exactly like Ansel Adams' zone system. Nothing whatsoever to do with 18 % grey and in practice very little to do with 12.8 % grey either. It is powerful, but the user has to know what he/she is doing. Dismissing spot meter as some exotic "only 18 % grey" mode which it isn't, is doing a disservice to those who want to learn. [/QUOTE]
