# Metering Modes **Metering modes** determine how your camera measures light in a scene to calculate exposure settings. The main types are: - **Evaluative/Matrix**: Analyzes the entire frame, often prioritizing focus points - **Center-weighted**: Emphasizes the middle of the frame - **Spot**: Measures light from a very small area (1-5% of frame) - **Partial**: Like spot but covers a slightly larger area (8-12%) ## Common Misconception **"Metering mode affects what parts of the image are sharp/in focus"** Many beginners confuse metering modes with **focus modes**. Metering only determines *exposure* (brightness) by telling the camera where to measure light. It has absolutely nothing to do with focus or sharpness. For example, using spot metering doesn't make that spot sharper—it just means the camera will expose the image based on the light reading from that specific spot.
