What do the various metering modes and icons mean?
Canon cameras support a number of different ways of metering light coming in through the lens. The midrange and professional models let you choose which metering mode you want, and consumer cameras generally default to evaluative in most settings with partial as an override option. Here are the various metering modes. Evaluative metering. Evaluative metering is the most automated metering mode. In this mode the image is divided into a number of zones – usually 3, 6, 16, 21 or 35. The camera s computer then looks at the metering zones and applies various algorithms (computer programs, essentially) to guess a likely exposure setting. It then chooses appropriate shutter and/or aperture settings based on these calculations. Unfortunately, Canon have not published details of how these algorithms work. Nikon, incidentally, call this type of metering matrix metering, and sometimes people use the term matrix to refer to all forms of multiple-cell computerized light metering. Evaluative meterin
