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 best 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. Larger aperture values indicate smaller apertures, and smaller aperture values indicate larger apertures. Backlight A light source to illuminate the monitor from behind the screen. CCD (Charge-Coupled Device) This converts light passing through the lens into electrical signals. With this camera, light is picked up and converted into RGB signals to build a single image. Contrast Detection Method This is used to measure the distance to the subject. The camera determines if the image is focused by the level of contrast in the subject. Conventional Photograph This refers to images recorded using silver halide (the method for recording images in conventional, non-digital photography). This system is different 10 from that used in still video and digital photography. DCF (Design rule for Camera File system) A standard for image files by the Japan Electronics and Information Technology Industries Association (JEITA). Miscellaneous 165
