Glossary of terms 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 This adjusts the amount of light that passes through the lens. Lower values allow more light to pass, while higher values lessen the amount of light. When you set the lowest aperture value for a lens, the aperture is at its widest. Conversely, the highest aperture value gives the narrowest aperture. Backlight A light source in the Monitor to let it be seen more easily. CCD (Charge-coupled Device) This converts light passing through the lens into electrical signals. On this camera, light is picked up at 2.11 million points 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 recording images using silver halide (the method for recording images in conventional, non-digital photography.) This system is in contrast to 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). Digital ESP (Electro-Selective Pattern) light metering This determines the exposure by metering and calculating the light levels in the center and other areas of the image separately. DPOF (Digital Print Order Format) This is for saving desired print settings on digital cameras. By entering which images to print and the number of copies of each, the user can automatically have the desired images printed by a printer or print lab that supports the DPOF format. 9 Eclipsing (Vignetting) This refers to when an object obscures part of the field of view so that the whole subject is not photographed. Vignetting also refers to when the image seen through the viewfinder does not exactly match the image shot through the objective lens, so the photographed image includes objects not seen through the viewfinder. In addition, vignetting can occur when an incorrect lens hood is used, causing shadowing to appear in the corners of the image. 195
