SUMMARY
But some scenes fool that approach badly, and that is where spot metering comes in. What Spot Metering Actually DoesYour camera's light meter can read the frame in a few different patterns. Like every metering mode, spot metering does not know what it is looking at. The fix is exposure compensation: when you meter off something that should stay bright, add exposure; when you meter off something that should stay dark, subtract exposure.
