Glossary of terms17310 AppendixEclipsing (Vignetting)This refers to when an object obscures part of the field of view so that the wholesubject is not photographed. Vignetting also refers to when the image seen throughthe viewfinder does not exactly match the image shot through the objective lens, sothe photographed image includes objects not seen through the viewfinder. Inaddition, vignetting can occur when an incorrect lens hood is used, causingshadowing to appear in the corners of the image.ESP (Electro-Selective Pattern) Light Metering/Digital ESP LightMeteringThis determines the exposure by metering and calculating the light levels in thecenter and other areas of the image separately.EV (Exposure Value)A system for measuring exposure. EV0 is when the aperture is at F1 and the shutterspeed is 1 second. The EV then increases by 1 each time the aperture increases byone F stop or the shutter speed increases by one increment. EV can also be used toindicate brightness and ISO settings.ExposureThe amount of light used to capture an image. The exposure is determined by thetime the shutter is open (shutter speed) and the amount of light that passes throughthe lens (aperture).Image sizeThe size of an image expressed by the number of pixels that make up the image. Forinstance, a picture taken with an image size of 640 × 480 fills the computer screenwhen the monitor setting is 640 × 480. However, if the monitor setting is1,024 × 768, the picture only takes up part of the screen.ISOA method for indicating film speed by the International Organization forStandardization (ISO) (ex. “ISO100”). Higher ISO values indicate greater sensitivityto light, so images can be exposed even in low-light conditions.JPEG (Joint Photographic Experts Group)A compression format for still images. Photographs (images) shot using this cameraare recorded onto the card in JPEG format when the record mode is set to SHQ, HQ,SQ1 or SQ2. By downloading these images to a personal computer, users can editthem using graphics application software or view the images using an Internet webbrowser.M (Manual) ModeThe user sets both the aperture and shutter speed.NTSC (National Television Systems Committee) / PAL (PhaseAlternating Line)Television formats. NTSC is mainly used in Japan, North America and Korea. PALis mainly used in Europe and China.P (Program) ModeAlso called Program AE mode. The camera automatically sets the best shutterspeed and aperture for the shot.
