Positive compensation No compensation | Negative compensation No flash |
Flash compensation changes the ratio between the ambient and flash exposures. When using fill- flash to reduce harsh shadows caused by direct sunlight, flash compensation changes the ratio between the highlights and shadows. The flash affects the darkness of the shadows without affect- ing the area illuminated by the sun. By decreasing the flash output with a negative Ev setting, the shadows receive less light and are deeper, but retain detail that would be lost without the flash. Using a positive Ev setting will soften or eliminate shadows.
Metering modes
Metering mode indicators are displayed on the monitor. The metering mode is set in section 2 of the P, A, S, and M menus (p. 44).
Center weighted: a traditional metering method in film cameras. The system measures light values over the entire image area with emphasis given the central region.
Spot metering: uses a small area within the image to calcu- late the exposure. A small circle appears in the middle of the live image indicating the measuring area. The spot allows precise exposure measurements of a particular object with- out being influenced by extremely bright or dark areas within the scene.
