Glossary
Exposure
The amount of light allowed to reach the camera’s sensor.
Exposure is controlled by a combination of the shutter speed, the
aperture value, and ISO sensitivity.
Flash
A speed light that helps to create adequate exposure in low-light
conditions.
Focal length
The distance from the middle of the lens to its focal point (in
millimeters). Longer focal lengths result in narrower angles of view
and the subject is magnified. Shorter focal lengths result in wider
angles of view.
Histogram
A graphical representation of the brightness of an image. The
horizontal axis represents the brightness and the vertical axis
represents the number of pixels. High points at the left (too dark)
and right (too bright) on the histogram indicate a photo that is
improperly exposed.
DPOF (Digital Print Order Format)
A format for writing printing information, such as selected images
and number of prints, on a memory card. DPOF-compatible
printers, sometimes available at photo shops, can read the
information from the card for convenient printing.
EV (Exposure Value)
All the combinations of the camera’s shutter speed and lens
aperture that result in the same exposure.
EV Compensation
This feature allows you to quickly adjust the exposure value
measured by the camera, in limited increments, to improve the
exposure of your photos. Set the EV compensation to -1.0 EV to
adjust the value one step darker and 1.0 EV to one step brighter.
Exif (Exchangeable Image File Format)
A specification to define an image file format for digital cameras
created by the Japan Electronic Industries Development
Association (JEIDA).
