State metering modes precisely and explain why it matters in 2-3 sentences.

# Metering Modes **Evaluative/Matrix Metering**: Analyzes the entire frame in multiple zones, comparing patterns to a database of thousands of scenes to determine optimal exposure. **Center-Weighted Metering**: Prioritizes the center 60-80% of the frame while considering the entire scene, assuming the main subject is centrally located. **Spot Metering**: Measures light from only 1-5% of the frame (usually the center focus point), ignoring everything else. **Partial Metering**: Similar to spot but covers ~9-15% of the frame, offering slightly more context than spot metering. ## Why It Matters Metering mode determines which part of your scene the camera uses to calculate exposure, directly affecting whether your subject is properly exposed or lost in shadow/highlight. Choosing the wrong mode can result in a correctly metered background but an underexposed subject (or vice versa), which is especially critical in high-contrast situations like backlighting or spotlit subjects.
