2012 Digital Cameras: Terms You’ll Hear
Aperture: The opening of a lens, which determines how much light can pass through it, described in terms of the lens’ f-stop.
CCD/CMOS: Types of imaging sensors, the light-sensitive chips that capture image information.
ISO: A rating that indicates the image sensor’s sensitivity to light. The higher the ISO rating, the harder the camera tries to capture details in low light. Too high an ISO, though, can make your pictures look grainy or speckled.
Image stabilization: A way to improve the picture quality by reducing the effect of camera movement while capturing a photo or video. It may also be referred to as anti-shake or vibration reduction, and some camera makers have their own names for this technology.
RAW: An image file format containing all the information captured by the sensor. An option in DSLRs and some point-and-shooters, it gives you the most options to edit or adjust an image.
