I see that Contax has introduced a new type of metering system on the Aria, what is Evaluative light metering?
A. Evaluative light metering, sometimes called segmented light metering is a system that breaks up the scene into five exposure areas. Then each is evaluated according to its location in the scene. Finally each is weighted according to a computer algorithm and integrated to produce a combination of shutter speed and f stop for exposure control. This new technology basically eliminates the need for exposure compensation because it weighs the brightness of back-light against the darkness of shadow and opts for over-exposing the highlight and preserving detail in the foreground.
