Peter, this is exactly what I meant: bearing in mind ETTL's AF point biasing, I wouldn't put the sensor onto the wtite/black pattern, but rather on subject's face. Putting it on white, the ETTL would give be heavily weighted to this tone and indeed will underexpose, however, regular "caucasian" face tone is much closer to 18% gray, though theoretically still may require about 1/3 - half stop compensation in certain situation. This is my opinion. What would you say ? ------------------------------------------------------------------------ --------------------- Alex, Think it through a bit further. Even though the main poiint is on the face, the matrix includes the white gown which will be averaged into the scene. I have done this and can tell you that you still need to compensate. Besides, not all caucasian skin tones are alike. Some fair, some olive, some in the middle, and each will alter the metering. Hence, I would suggest you try what I say and see how it works. Sometimes over analyzing something does not help.
