Basic Photography: Optical and Digital Zoom30Optical and Digital ZoomThe COOLPIX 990 is equipped with motor-driven, ×3 opticalzoom linked to the viewfinder. By changing the area visible inthe viewfinder (the “field of view”), zoom helps you establishthe right balance between subject and background. A widefield of view is suitable for group portraits or landscapes, anarrow field of view for close-ups or long-range photography.Digital zoom can be used to further enlarge photographs elec-tronically by up to ×4.0. Note that zooming in on a subjecttends to decrease the amount of light entering the camera,resulting in slower shutter speeds, while simultaneously de-creasing the apparent distance between the subject and thebackground. Zooming out has the opposite effect.Optical ZoomPhotos can be framed in the viewfinder or LCD monitor usingthe zoom buttons.P 1/601/60 F 2.72.7 NORMALNORMAL[ 1010]Indicator in LCDmonitor displays amountof zoom while eitherbutton is pressedZoom inZoom outDigital ZoomAt the maximum optical zoom position, holding the but-ton down for two seconds triggers digital zoom.While digital zoom is in effect, the zoom factor increases eachtime the button is pressed, to a maximum of ×4.0.
