Glossary
AdobeRGB
Color space recommended by Adobe Systems, Inc. for commercial
printing. Wider range of color reproduction than sRGB. Covers most of the
color range so colors only available when printed are not lost when editing
images on a computer. When image is opened by non-compatible
software, the colors look lighter.
AE Metering
Brightness of subject is measured to determine exposure. In this camera,
select from [Multi-segment Metering], [Center-weighted Metering] and
[Spot Metering].
Aperture
The aperture increases or reduces the light beam (thickness) passing
through the lens to the CCD.
Auto Bracket
For automatically changing exposure. When the shutter button is pressed,
three images are shot. The first one has no compensation, the second is
underexposed and the third is over-exposed.
Bright Portion
Overexposed area in the image loses contrast and appears white.
Camera Shake (Blur)
When the camera moves while the shutter is open, the entire image
appears blurred. This occurs more often when shutter speed is low.
Prevent camera shake by raising the sensitivity, using the flash, and
raising the shutter speed. Alternatively, use a tripod to stabilize the
camera. As camera shake is mostly likely to occur when pressing the
shutter release button, use the Shake Reduction function, the self-timer,
the remote control unit, or the cable switch to prevent camera movement.
CCD (Charge Coupled Devices)
Photography element which converts the light entering through the lens
into electric signals that create the image.
