Generation

# Metering Modes Metering modes determine how a camera measures light in a scene to calculate proper exposure. The main modes are **evaluative/matrix** (analyzes the entire frame in zones), **center-weighted** (prioritizes the middle 60-80% of the frame), **spot** (measures only 1-5% of the frame), and **partial** (measures ~9-12% of the center). **Key formula**: All modes aim to achieve proper exposure using: **EV = log₂(N²/t)** or practically: **Aperture + Shutter Speed + ISO = Correct Exposure** The camera meters to expose the scene to middle gray (18% reflectance), though different modes weight various parts of the frame differently.
