recharged many times. NiMH batteries provide sufficient power to run digital cameras and flashes.

Online photo printer A company that receives digital photos uploaded to its Web site, prints them, then sends the prints back by mail or courier.

Panning

A photography technique in which the camera follows a moving

 

subject. Done correctly, the subject is sharp and clear, while the

 

background is blurred, giving a sense of motion to the photo.

Pixel

Picture Element: digital photographs are comprised of thousands

 

or millions of them; they are the building blocks of a digital photo.

RAW

The RAW image format is the data as it comes directly off the

 

CCD, with no in-camera processing is performed.

Red-eye

The red glow from a subject's eyes caused by light from a flash

 

reflecting off the blood vessels behind the retina in the eye. The

 

effect is most common when light levels are low, outdoor at night,

 

or indoor in a dimly-lit room.

RGB

Red, Green, Blue: the three colors to which the human visual

 

system, digital cameras and many other devices are sensitive.

Saturation

How rich the colors are in a photo.

Sensitivity

See ISO speed.

Serial

A method for connecting an external device such as a printer,

 

scanner, or camera, to a computer. It has been all but replaced by

 

USB and FireWire in modern computers.

Sharpness

The clarity of detail in a photo.

Shutter speed

The camera's shutter speed is a measurement of how long its

 

shutter remains open as the picture is taken. The slower the

 

shutter speed, the longer the exposure time. When the shutter

 

speed is set to 1/125 or simply 125, this means that the shutter

 

will be open for exactly 1/125th of one second. The shutter speed

 

and aperture together control the total amount of light reaching

 

the sensor. Some digital cameras have a shutter priority mode

 

that allows you to set the shutter speed to your liking. See also

 

aperture.

SmartMedia™

A wafer-thin, matchbook size memory card. This is also a flash-

 

memory based storage medium.

Thumbnail

A small version of a photo. Image browsers commonly display

 

thumbnails of photos several or even dozens at a time. In

 

Windows XP's My Pictures, you can view thumbnails of photos in

 

both the Thumbnails and Filmstrip view modes.

USB

Universal Serial Bus: a protocol for transferring data to and from

 

digital devices. Many digital cameras and memory card readers

 

connect to the USB port on a computer. USB card readers are

 

typically faster than cameras or readers that connect to the serial
