Glossary Shutter speed Shutter speed refers to the amount of time it takes to open and close the shutter, and it is an important factor in the brightness of a photo, as it controls the amount of light which passes through the aperture before it reaches the image sensor. A fast shutter speed allows less time to let light in and the photo becomes darker and more easily freezes subjects in motion. Vignetting A reduction of an image's brightness or saturation at the periphery (outer edges) compared to the center of the image. Vignetting can draw interest to subjects positioned in the center of an image. White balance (color balance) An adjustment of the intensities of colors (typically the primary colors red, green, and blue), in an image. The goal of adjusting the white balance, or color balance, is to correctly render the colors in an image. Appendixes 124

Glossary
Shutter speed
Shutter speed refers to the amount of time it takes to open and
close the shutter, and it is an important factor in the brightness of
a photo, as it controls the amount of light which passes through
the aperture before it reaches the image sensor. A fast shutter
speed allows less time to let light in and the photo becomes
darker and more easily freezes subjects in motion.
Vignetting
A reduction of an image’s brightness or saturation at the periphery
(outer edges) compared to the center of the image. Vignetting
can draw interest to subjects positioned in the center of an
image.
White balance (color balance)
An adjustment of the intensities of colors (typically the primary
colors red, green, and blue), in an image. The goal of adjusting
the white balance, or color balance, is to correctly render the
colors in an image.
