Glossary of terms
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.
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 indicated by 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. Shadows on the subject can be
changed by detaching the flash. The flash is used in combination with the flash cable.
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 exposed even in low-light conditions.
JPEG (Joint Photographic Experts Group)
A compression format for still images. Photographs (images) shot using this camera are
recorded onto the card in JPEG format when the record mode is set to SHQ, HQ, SQ1 or
SQ2. 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.
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.
Phase-difference Detection System
This system measures the distance to the subject. The distance is calculated by the
difference in the image of the subject captured by a pair of sensors.
Pixels
A pixel is the smallest unit (dot) used to make up an image. Clear large-sized printed
images require millions of pixels.
