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's built-in exposure meter
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
This adjusts the amount of light that
passes through the lens. Lower values
allow more light to pass, while higher
values lessen the amount of light.
When you set the lowest aperture value
for a lens, the aperture is at its widest.
Conversely, the highest aperture value
gives the narrowest aperture.
Backlight
A light source in the Monitor to let it be
seen more easily.
CCD (Charge-coupled Device)
This converts light passing through the
lens into electrical signals. On this
camera, light is picked up at 2.11 million
points 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.
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
automatically have the desired images
printed by a printer or print lab that
supports the DPOF format.
Eclipsing (Vignetting)
This refers to when an object obscures
part of the field of view so that the
whole subject is not photographed.
Vignetting also refers to when the
image seen through the viewfinder
does not exactly match the image shot
through the objective lens, so the
photographed image includes objects
not seen through the viewfinder. In
addition, vignetting can occur when an
incorrect lens hood is used, causing
shadowing to appear in the corners of
the image.
