Glossary

Appendix

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.

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

Depth of Field refers to the distance from the nearest to the furthest point of

perceived "sharp" focus in a picture.

Digital ESP (Electro-Selective Pattern) Light Metering

This determines the exposure by splitting the image into 49 areas and

metering and calculating the light levels in each area.

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.
