A (Aperture Priority) Mode
You set the aperture yourself and the camera automatically varies the shutter
speed so that the picture is taken with the correct exposure.
AE (Automatic Exposure)
The camera’s built-in exposure meter automatically sets the exposure. The 3 AE modes
available on this camera are P mode, in which the camera selects both the aperture and shutter
speed, A mode, in which the user selects the aperture and the camera sets the shutter speed,
and S mode, in which the user selects the shutter speed and the camera sets the aperture.
In M mode, the user selects both the aperture and the shutter speed.
Aperture
The adjustable lens opening which controls the amount of light that enters the
camera. The larger the aperture, the shorter the depth of field and the fuzzier the
background. The smaller the aperture, the greater the depth of field and the
sharper the background. Aperture is measured in f/stops. Larger aperture values
indicate smaller apertures, and smaller aperture values indicate larger apertures.
CCD (Charge-Coupled Device)
This converts light passing through the lens into electrical signals. On this camera,
light is picked up and converted into RGB signals to build a single image.
Center weighted averaging metering
A light metering mode or technique that uses an average of the center and periphery
of the image area but is biased toward the information at the center of the image area.
This method is best used when the brightness of the center and periphery of the image
area does not vary greatly. See also digital ESP metering and spot metering.
Color space
A model that describes colors using more than three coordinates. Color spaces such
as sRGB, Adobe RGB are occasionally used for encoding/reproducing colors.
Color temperature
The spectral balance of different white light sources is rated numerically by color
temperature — a concept of theoretical physics that, with incandescent lighting,
corresponds roughly to the absolute lamp filament temperature, expressed on the
Kelvin (K) temperature scale. The higher the color temperature, the richer the light in
bluish tones and the poorer in reddish; the lower the color temperature, the richer the
light in reddish tones and the poorer in bluish. You may encounter difficulties with color
reproduction when shooting indoors under fluorescent lighting, or where sunlight and
fluorescent lighting are both present. Your camera is provided with a white balance
adjustment feature that you can use to compensate for the odd effects of combinations
of color you may occasionally see in your pictures.
