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
an image is opened by non-compatible software, the colors look lighter.
Auto Bracketing
For automatically changing exposure. When the shutter release button is
pressed, several images are captured. One has no compensation, one or
more are underexposed, and one or more are overexposed. This camera
features Exposure Bracketing that captures images in different exposures,
and Extended Bracketing that captures images with set White Balance,
Saturation, Hue, High/Low Key Adjustment, Contrast and Sharpness
levels.
AE Metering
Brightness of subject is measured to determine exposure. In this camera, select
from [Multi-segment Metering], [Center-weighted Metering] and [Spot Metering].
AF point
Position in the viewfinder that determines focus. In this camera, select
from [Auto], [Select] and [Center].
Aperture
The aperture increases or reduces the light beam (thickness) passing
through the lens to the CMOS sensor.
Bright Portion
Overexposed area in an 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 most likely to occur when pressing the shutter
release button, use the Shake Reduction function, Self-timer or Remote
Control shooting to prevent camera movement.
