Spot metering is the process of reading reflected light levels from a very small area, typically 1-3% of an image area.
Most high-end SLRs have internal spot meters, which are particularly important for users of the zone system of light metering. This type of metering is often indicated on cameras by a spot metering icon.
You can also purchase external spot meters. These are handheld devices with little sights through which you can peer and select areas to meter.
