Glossary A (Aperture Priority) Mode You set the aperture yourself and the camera automatically varies the shutter speed so that the picture is taken with the correct exposure. AE (Automatic Exposure) The camera's built-in exposure meter automatically sets the exposure. The 3 AE modes available on this camera are P mode, in which the camera selects both the aperture and shutter speed, A mode, in which the user selects the aperture and the camera sets the shutter speed, and S mode, in which the user selects the shutter speed and the camera sets the aperture. In M mode, the user selects both the aperture and the shutter speed. Aperture The adjustable lens opening which controls the amount of light that enters the camera. The larger the aperture, the shorter the depth of field and the fuzzier the background. The smaller the aperture, the greater the depth of field and the sharper the background. Aperture is measured in f/stops. Larger aperture values indicate smaller apertures, and smaller aperture values indicate larger apertures. AUTO mode Program AE mode (see "P (Program) Mode"). In addition, this mode features automatic flash pop up when shooting in low-light conditions. CCD (Charge-Coupled Device) This converts light passing through the lens into electrical signals. On this camera, light is picked up and converted into RGB signals to build a single image. Center weighted averaging metering A light metering mode or technique that uses an average of the center and periphery of the image area but is biased toward the information at the center of the image area. This method is best used when the brightness of the center and periphery of the image area does not vary greatly. See also digital ESP metering and spot metering. Color space A model that describes colors using more than three coordinates. Color spaces such as sRGB, Adobe RGB are occasionally used for encoding/ reproducing colors. Appendix 11 177
