Digital camera: a camera that captures the photograph using an electronic imaging sensor to record data in pixels on a memory card instead of on traditional film.
Digital zoom: a zoom lens that moves closer to the subject by cropping the image within the LCD screen. The drawback to a digital zoom is the loss of quality. A digital zoom is essentially no different than cropping and editing in a digital photography software program.
Optical zoom: a zoom lens that moves your view closer to the subject without losing photographic quality. It is the traditional zoom lens.
Flash card: a memory card designed for use in your camera that uses flash memory. There are several types of flash cards.
Flash memory: a memory chip that retains the data after being shut off.
Image resolution: the number of pixels in a digital photograph.
Lag time: the time that elapses between when the shutter release is pressed and the camera takes the photograph. Most digital camera models except digital SLRs experience shutter lag.
Liquid Crystal Display (LCD) screen: a viewing window that allows previewing or reviewing of images and allows camera settings to be changed.
Memory card: small card inserted into the camera, used to store images. Images are downloaded from the card, generally to a computer, and the card can then be reused.
Memory stick: a small memory card for storing photographs using flash memory.
ISO Speed: Similar to the traditional film camera rating system, ISO speed is determined by the camera’s imaging sensor. As in traditional film cameras, the higher ISO, the lower the image quality.
