Exposure compensation, How much?
Under most situations, in which the subject is not a very bright white, or a very dark color, I have to shoot under by 2/3 to 1 full stop. A neutral gray subject will require this EC. Seens to make no difference which metering method I use, neither does the lighting optimizer.
I want to go to my grave, tires bald, fenders knocked off, out of gas, and yelling, WOW what a ride.
