Generation

# Metering Modes Metering modes determine how your camera measures light in a scene to calculate the proper exposure. **Evaluative/Matrix metering** analyzes the entire frame and is best for evenly-lit scenes, while **Center-weighted metering** prioritizes the middle of the frame where your subject usually is. **Spot metering** reads light from only a tiny area (usually 1-5% of the frame), giving you precise control when you want to expose for one specific element, like a face in harsh lighting or a backlit subject. Think of it like this: evaluative is the camera's "auto-pilot," center-weighted assumes your subject is in the middle, and spot metering lets you tell the camera exactly what matters most.
