With auto white balance, the camera attempts to determine the 
color temperature of the light and automatically adjust for that 
color temperature. Many people just leave the camera set to 
auto white balance all the time. 

A type of silicon integrated circuit used to convert light into an 
electronic signal. 

The process of encoding information using fewer bits cf. image 
compression, sound fi le compression 

A standardized ASCII fi le created in a digital camera and stored 
on removable media along with the image fi les that indicate how 
many copies of which images should be printed. It also allows 
index prints, cropping, and text overlays to be specifi ed. 

A camera incorporating an image sensor which outputs a digital 
signal representing a still picture, or records a digital signal 
representing a still picture on a removable medium, such as a 
memory card or magnetic disk.

cf. ISO DSC dynamic range, colour gamut, luminance ratio

A compressed fi le format for digital cameras in which the images 
are compressed using the baseline JPEG standard, described in 
ISO 12234-2, and metadata and thumbnail images are stored 
using TIFF tags within an application segment at the beginning 
of the JPEG fi le. 

A numerical value that is inversely proportional to the exposure 
provided to an image sensor to obtain an image. Images 
obtained from a camera using a range of exposure index values 
will normally provide a range of image quality levels. 

A numerical value calculated from the exposure provided at the 
focal plane of an electronic camera to produce specifi ed camera 
output signal characteristics using the methods described in the 
referenced standard. The ISO speed should correlate with the 
highest exposure index value that provides peak image quality 
for normal scenes.
