Digital Camera Terms & Tips

Some common digital camera terms we hear and what they mean:

ISO: Traditionally used as an indicator of sensitivity for film cameras, ISO on modern digital cameras represents the camera’s sensitivity to light. Generally, the darker the scene, the higher the ISO should be set.

APERTURE: The aperture, or “f-stop” to the film purists, is the amount of light the lens lets into the camera. This can be adjusted in single-lens reflex cameras. The aperture is fixed for most point-and-shoots.

IMAGE STABILIZATION: This refers to a part of the digital camera, built into the body or the lens, that prevents “camera shake” in pictures.

DIGITAL/OPTICAL ZOOM:

• OPTICAL ZOOM refers to the manual zoom on a camera, which is located on the lens. Twisting the lens moves it closer to the subject. This is important – they higher the optical zoom the more “zoom” ability you have – 3x optical zoom was common, but today many cameras have 10x & 12x zoom..
• DIGITAL ZOOM is not used by moving the lens, rather it is part of the software of the camera. Most digital cameras – even point-and-shoots – have a form of both. Many consider digital zoom – camera hype…

CONTINUOUS PHOTO SPEED/BUFFER: Every digital camera has continuous photo speed; the number you set it on is the number of photos you can take per second. The faster the camera’s continuous speed, the more photos you can get per second.
