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.
