Adobe Photoshop make use of
EXIF data to display thumbnails
in the program’s Bridge image-
management module. Clicking on
a thumbnail in Photoshop Ele-

previous ones is the color space that used. Color space describes
the range of reproducible colors that a camera can see, a printer

sRGB (Standard RGB) color space and colors are limited to
reproduction within this range. Some digital cameras, however,
use the sYCC color space, which allows a wider range of colors
to be recorded and reproduced than does sRGB.
Long used in the video world and in Kodak’s original Photo CD
format, YCC represents the familiar Red, Green, and Blue (RGB)
channels as a luminance (Y) and two color-difference channels,
