Miscellaneous
EV • • • • • • • • • • • • • • • • • • • • • • • • •
(Exposure Value)
An exposure measurement system in
which the exposure for an aperture of F1
and a shutter speed of 1 second is
taken as EV0. The EV value 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 for which 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 laid
down by the International Organization
for Standardization (ISO) (e.g. "ISO
100"). Higher ISO values indicate
greater sensitivity to light so that images
can be exposed even in low-light condi-
tions.
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 • • • • • • • • • • • • • •
A shooting mode in which the user sets
both the aperture and the shutter speed.
P (Program) Mode • • • • • • • • • • • • • •
Also called Program AE mode. In this
mode, the camera automatically sets
the optimal shutter speed and aperture
setting for the shot.
Glossary of terms
Pixels • • • • • • • • • • • • • • • • • • • • • •
A pixels the smallest unit (dot) used to
make up an image. Large size clear
printed images require large number of
pixels.
Ring Flash • • • • • • • • • • • • • • • • • • •
A flash unit that uses a circular xenon
fluorescent tube as the light source.
S (Shutter Priority) Mode • • • • • • • • •
Also called Shutter Priority AE mode. In
this mode, the user selects the shutter
speed and the camera automatically
varies the aperture according to the
shutter speed setting so that the picture
is taken with the optimum exposure.
Synchro Terminals • • • • • • • • • • • • •
Terminals on an external flash unit that
are used for connecting to the camera.
TFT (Thin-Film Transister) Color
Monitor • • • • • • • • • • • • • • • • • • • • •
A color Monitor constructed using thin-
film technology.
TIFF • • • • • • • • • • • • • • • • • • • • • • • •
(Tagged Image File Format)
A format used for saving black and
white and color image data. TIFF image
files can be handled by software pro-
grams for scanners and graphics appli-
cations.
TTL (Through-The-Lens) System • • •
An exposure adjustment mechanism in
which a light receptor built into the cam-
era directly measures the light passing
through the lens.
TTL-AUTO • • • • • • • • • • • • • • • • • • •
An external flash unit function. This is a
control method in which the light emitted
by the flash is received and measured
by the light receptor in the camera as it
passes through the lens. A flash intensi-
ty control signal is then generated using
that light and sent to the flash unit.
