<< I only
know of one (well 2
actually, one analog, the other digital) spotmeter that is colour linear.
Let us use as an example, you are photographing a scene with a red barn, and
blue sky. Maybe there is a field of green wheat in the forground. There are
no neutral colours to meter. If your meter is a typical cell, then it has a
colour bias. It will not give an accurate reading of anything in the scene.
That red barn will be out by 2 stops if you read it, the blue sky will be
out by at least a stop, and the wheat field will also be inaccurately
exposed. >>
Don't the silicon metering cells have a filter over them to adjust the color
sensitivity to the color sensitivity of the average slide/negative film? I
though they all did.
