Glossary of Selected Terms (continued)
color temperature
The spectral balance of different white light sources is rated numerically by color temperature—a concept of
theoretial 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 and
the poorer in reddish; the lower the color temperature, the richer the light in reddish 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 color combinations of color you may occasionally see in
your pictures.
CompactFlash
A memory card which can be inserted in the camera for storing images. The number of images that you can store
on one card depends on the size of the images which is determined by the record mode setting (quality,
resolution, compression) when the pictures are taken.
CompactFlash memory card adapter
A device which enables a computer to read images from the memory card. The memory card is removed from the
camera and inserted into the memory card adapter, then the memory card adapter with the memory card inserted
are loaded in the card slot of the computer.
DCF
Denotes
Design rule for Camera Files
. A camera file system standard employed with this camera and other digital
cameras.
difficult subjects
These are subjects which are difficult to focus with the autofocus and autoexposure features. Generally, you may
find it difficult to use autofocus with (1) subjects of low contrast, (2) subjects immersed in very bright light, (3)
subjects without vertical lines, (4) subjects at different distances from the camera, (4) and fast moving subjects.
Digital ESP metering
ESP denotes
Electro Selective Pattern
. The picture composed in the viewfinder is divided into several equal
sections and then the metered readings of these sections are averaged. A sunset or sunrise is ideal for this
method of metering because each section of the picture is metered separately and then averaged so the sun does
not disrupt the reading.
diopter adjustment
Allows eyeglass wearers to focus the AF target mark in the viewfinder. If you wear eyeglasses and the AF target
mark is difficult to see in the viewfinder, adjust the view with the diopter adjustment ring. Turn the diopter
adjustment ring until you see the AF target mark come into sharp focus.
DPOF
Means
Digital Print Order Format
. A format standard used by DPOF-compatible printers employed by printing
services which allow you to get more reliable photofinishing services using memory cards. You can specify which
pictures that you want printed, whether to stamp the prints with the time or date, the number of copies to print, and
whether prints are to be single or multiple (index printing).
EV
An abbreviation for
Exposure Value
. EV=0 with the aperture stopped at f/1 and shutter speed is set for 1 second
with ISO at 100. The EV value increases by 1 as the aperture is stopped up by 1 stop, or if shutter speed is
increased by 1 step. Conversely, the EV value decreases by 1 for every aperture stop below 1, or if shutter speed
is decreased 1 step. If the ISO is adjusted, EV increases by one if the ISO setting is doubled, and decreases by 1
if the ISO setting is halved.
exposure
Generally the amount of light used to create an image. The amount of light is controlled by the shutter speed and
the size of the aperture when the picture is taken.
exposure compensation
Manually increasing or decreasing the exposure which has been set by AE (automatic exposure). When exposure
is increased, this is called plus compensation, and when decreased, this is called minus compensation.
file format
Usually refers to the file structure of images and documents. This camera can handle images in three formats:
TIFF, JPEG, and RAW. The TIFF and JPEG formats are standard computer graphic file formats and can be used
with most graphic software applications.
