Glossary of terms

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 best exposure.

AE (Automatic Exposure)

The camera 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.

Contrast Detection Method

This is used to measure the distance to the subject. The camera determines

if the image is focused by the level of contrast in the subject.

Conventional Photograph

This refers to recording images using silver halide (the method for recording

images in conventional, non-digital photography). This system is in contrast

to still video and digital photography.

DCF (Design rule for Camera File system)

A standard for image files by the Japan Electronics and Information

Technology Industries Association (JEITA).

Digital ESP (Electro-Selective Pattern) Light Metering

This determines the exposure by metering and calculating the light levels in

the center and other areas of the image separately.
