Interesting. I too have found that foliage, trees, mountains, which are all typical of an Ansel Adams photograph, are very close to 18%. On the other hand, typical caucasian skin is at about zone VI or 13%. And since most cameras are used to take snapshots of the rug rats, a meter calibrated to

I am the one who argues that this 13% thing is bull. Take your incident meter and meter a gray card in reflected mode. Then take an incident mode reading. The readings will be the same. If the meter was calibrated for 13% gray the readings would be different because that dome is definitely 18%

Hi, this assumes that most camera users are white, which is a highly dubious assumption given that most people are not white. It would be commercial suicide to base meter calibration on any particular skin colour. If it's true that white skin is about 13% then I'd suggest it's probably

Tom R. exploded: I am the one who argues that this 13% thing is bull. Tom, Actually it's not. The ANSI standard is around 12% and a lot of manufacturers use 13%. Of course, as with film speed, the manufacturers do what they want to do, so many of them do calibrate to 18%. I wouldn't be

Well, Mike, even if the meters are setup for a 13% gray, and I still doubt that because as I have said my Sekonic 308 gives the same reading with light reflected for an 18% gray card as it does in incident mode, all you have to do is reduce your ASA by that amount and use 18% because all that is

A couple of weeks ago there was some discussion here about how the camera manufactures are calibrating their meter to 13% rather than 18%. Someone commented that Kodak is now suggesting that you open up a 1/3 to 1/2 when using a gray card to set exposure. WHAT 18% gray was chosen because
