Glossary of terms (Cont.)
EV (Exposure Value)
A system for measuring exposure. EV0
is when the aperture is at F1 and the
shutter speed is 1 second. The EV then
increases by 1 each time the aperture
increases by one F stop or the shutter
speed increases by one increment. EV
can also be used to indicate brightness
and ISO settings.
Exposure
The amount of light used to capture an
image. The exposure is determined by
the time the shutter is open (shutter
speed) and the amount of light that
passes through the lens (aperture).
Flash Bracket
A mount used to attach an external
flash to the camera.
ISO
A method for indicating film speed by
the International Organization for
Standardization (ISO) (e.g. "ISO100").
Higher ISO values indicate greater
sensitivity to light, so images can be
9
exposed even in low-light conditions.
JPEG (Joint Photographic Experts
Group)
A compression format for color still
images. Photographs (images) shot
using this camera are recorded onto the
SmartMedia card in JPEG format when
the Record mode is set to SHQ, HQ or
SQ. By downloading these images to a
personal computer, users can edit them
using graphics application software or
view the images using an Internet web
browser.
M (Manual) Mode
The user sets both the aperture and
shutter speed.
P (Program) Mode
Also called Program AE mode. The
camera automatically sets the best
shutter speed and aperture for the shot.

Pixels
A pixel is the smallest unit (dot) used to
make up an image. Clear large-sized
printed images require a large number
of pixels.
Ring Flash
A flash unit that uses a circular xenon
fluorescent tube as its light source.
S (Shutter Priority) Mode
Also called Shutter Priority AE mode.
The user selects the shutter
speed and the camera automatically
varies the aperture so that the picture is
taken with the best exposure.
Synchro Terminals
Terminals on an external flash unit for
connecting it to the camera.
TFT (Thin-Film Transistor) Color
Monitor
A color Monitor constructed using thin-
film technology.
TIFF (Tagged Image File Format)
An uncompressed format used for
saving highly-detailed black & white or
color image data. TIFF image files can
be handled by software programs for
scanners and graphics applications.
TTL (Through-The-Lens) System
To help adjust exposure, a light
receptor built into the camera directly
measures the light passing through the
lens.
TTL-AUTO
For use with an external flash. Light
emitted by the flash is measured by the
light receptor in the camera as it passes
through the lens. A signal is then sent to
adjust the external flash's intensity.
