G
gamma
The range of color values a monitor, scanner, or printer can display. Adjusting this
value increases or decreases the intensity of the light spectrum. A gamma correct-
ed image simulates the adjusted display value when it is saved.
H
hue
The value of the color in the visible spectrum. A color with a minimum value is
red. As the value increases the color changes, but the lightness and saturation
remain the same. One of the three components of the HSL mode.
I
image resolution
This refers to the sharpness and clarity of an image and is used to describe moni-
tors, printers, and bit-mapped graphic images.
image sequences
When you view more than one image file you are viewing an image sequence.
When multiple images are opened, the Viewer displays them one at a time. The
image sequence can be seen in the lower left corner of the View window status
bar.
J
jaggies
The jagged stair-stepping effect often seen in images whose resolutions are so
low that individual pixels are visible.
L
lightness/luminescence
The brightness value of a color. A color with a maximum lightness is white. A color
with a minimum lightness is black. One of the three components of the HSL
mode.
lossless compression
The image is compressed without losing image quality.
lossless rotation
Lossless rotation happens when an unmodified JPEG image is rotated. When the
image is rotated it maintains all the pixels in the exact location as the original
image. The best JPEG images for rotation are obtained from digital cameras, as
they are preformatted to the correct dimensions. The dimensions must be a multi-
ple of 8 or 16.
