Parts of a Digital Camera

If you're very new to digital cameras, you might be wondering what all those buttons, LEDs, and windows are for. Here's a quick introduction to the key components of the average non-SLR digital camera. Not every camera will have all these features, and some will have additional features not shown in Figures 1-1 and 1-2.

♦ Shutter release: Depressing this button halfway locks exposure and focus; press all the way to take a picture.

♦ Control buttons: Miscellaneous control buttons might turn on/off close-up mode, automatic flash, or other features; set picture quality; or activate self-timer.

♦ Shooting mode dial: Most cameras use this button for changing among different scene modes (such as Night, Portrait, or Sports), adjust automatic or manual exposure choices, select Movie mode, or switch into close-up mode.

♦ Microphone: This captures audio for movie clips and voice annotations; it can even activate a sound-triggered self-timer.

♦ Focus-assist light: This is an auxiliary illumination source that helps the camera focus in dim lighting conditions.

♦ Electronic flash: This provides light under dim conditions or helps fill in dark shadows.

♦ Optical viewfinder: This window is for framing and composing your picture.

♦ Zoom lens: This magnifies and reduces the size of the image, taking you closer or moving you farther away.

♦ Tripod socket: This allows you to attach the camera to a firm support, such as a tripod or monopod, plus other accessories, such as an external flash bracket.

♦ Docking port: Some cameras have a special dock that can be used to transfer photos, recharge the batteries, make prints, or other functions.

♦ Battery compartment: This contains the cells that power the camera.

♦ Power switch: Here is where you turn the camera on or off.

♦ Indicator LEDs: These lights show status, such as focus and exposure, often with green and red go/no go LEDs (light-emitting diodes).

♦ LCD (liquid crystal display) panel: This shows the sensor's view of an image before exposure, previews images after exposure, displays status, photo information, and menus.

♦ Print/e-mail photos: Some digital cameras allow printing directly from the camera to compatible printers, or marking pictures for printing or e-mailing later.

♦ Set/Execute button: Press this to activate a feature or set a menu choice to the current selection.

♦ Memory card slot: This accepts digital memory cards.

♦ USB port: Use this to connect your camera directly to your computer or a printer via a USB cable.
