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.
AUTO mode
Program AE mode (see “P (Program) Mode”). In addition, this mode features automatic flash

pop up when shooting in low-light conditions.
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.
Compression rate
Compression is a method of reducing file size by abbreviating some contents of data, and
compression rate denotes the amount of compression. The actual effect of the selected

compression rate could vary with the content of the image. The numbers for the compression

rate selected with this camera provide only a general scale for reference and are not precise

measurements.
DCF (Design rule for Camera File system)
A standard for image files by the Japan Electronics and Information

Technology Industries Association (JEITA).
Depth of Field
Depth of Field refers to the distance from the nearest to the furthest point of perceived “sharp”

focus in a picture.
