The Must-Know Digital Camera Terms

By Kathleen Burch


When learning to use your new digital camera, it also helps to know what some of the more common terms mean. Here are some common terms that you would need to know.

Defining Automatic Mode. This is a setting that sets the focus, exposure, and white-balance automatically.

Burst Mode or Continuous Capture Mode. These are a series of pictures that are taken one after another at quickly timed intervals with one press of the shutter button.

Defining Compression. By deleting selected information, this process compacts digital data, images, as well as text.

Digital Zoom. Here, the center part of an image is cropped and magnified. What is JPEG? This predominant format is used for image compression in digital cameras. Lag Time. This refers to the pause between the time the shutter button is pressed and when the camera actually captures the image.

What is LCD? (Liquid-Crystal Display) is a small screen on a digital camera for viewing images.

Defining Lens. This refers to a circular and transparent glass or plastic piece that has the function of collecting light and focusing it on the sensor to capture the image.

Megabyte. Megabyte, or MB, measures 1024 Kilobytes and it also refers to the amount of information in a file, or how much information can be contained on a Memory Card, Hard Drive or Disk.

Pixels. Making up digital pictures are these tiny units of color. Pixels also measure digital resolution. One million pixels adds up to one mega-pixel.

RGB. This is known as the red, green, and blue colors used on computers so that all other colors can be created.

Resolution. Camera resolution determines the amount of detail a camera can capture and it also describes the number of pixels used to create the image. The more pixels a camera has, the more detail it can register and the larger the picture can be printed.

What is Storage Card? This removable storage device is much smaller and it holds images taken with the camera, comparable to film. It's also known as digital camera memory card.

Defining a viewfinder. The optical "window" to look through to compose the scene.

Defining White Balance. You can use white balancing in order to adjust the camera to compensate for the type of light (daylight, fluorescent, incandescent, etc.) or lighting conditions in the scene so it will look normal to the human eye.
