Custom Style Presets
Metering determines how the camera measures light to calculate exposure. Different modes work better for different shooting scenarios.
Evaluates the entire frame and calculates balanced exposure. Excellent for most situations with varied lighting. Default recommendation.
Prioritizes the center of the frame while considering edges. Good for centered subjects with different backgrounds.
Measures only a small area (linked to focus point). Perfect for backlit subjects or precise exposure control.
Prevents highlight clipping by prioritizing bright areas. Ideal for stage performances and high contrast scenes.
