Appendix
ISO
A method for indicating film speed by the International Organization for
Standardization (ISO) (ex. “ISO100”). Higher ISO values indicate greater sensitivity
to light, so images can be exposed even in low-light conditions.
JPEG (Joint Photographic Experts Group)
A compression format for still images. Photographs (pictures) taken using this
camera are recorded onto the card in JPEG format. By downloading these images
to a 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.
Noise reduction
When shooting in dark places, shutter speeds become slower as there is less light
focused on the CCD. During long exposures, signals are generated by parts of the
CCD where no light is focused and are recorded on the picture as noise. When noise
reduction works, the camera automatically reduces the noise to produce clearer
images.
NTSC (National Television Systems Committee) / PAL (Phase
Alternating Line)
Television formats. NTSC is mainly used in Japan, North America and Korea. PAL
is mainly used in Europe and China.
P (Program) Mode
Also called Program AE mode. The camera automatically sets the best shutter
speed and aperture for the shot.
PictBridge
A standard for connecting digital cameras and printers of different makers and
printing out pictures directly.
Pixels
A pixel is the smallest unit (dot) used to make up an image. Clear large-sized printed
images require millions of pixels.
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.
Slave Flash
A wireless flash that is not connected to the camera by a synchronization cord. It
flashes in phase with the flash on the camera and can be used for lighting
techniques, such as changing the way shadows are cast on a subject.
