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. Larger aperture values indicate smaller apertures, and smaller

aperture values indicate larger apertures.

Backlight

A light source to illuminate the monitor from behind the screen.

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).

Depth of Field

The subject itself as well as some area to the front and rear of the subject are

focused. The entire depth of this focused area, from the front to the rear of the

subject, is called “depth of field”.

DPOF (Digital Print Order Format)

This is for saving desired print settings on digital cameras. By entering which images

to print and the number of copies of each, the user can easily have the desired

images printed by a printer or print lab that supports the DPOF format.
