Glossary EV Compensation All the combinations of the camera's shutter speed and lens aperture that result in the same exposure. EV (Exposure Value) 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). 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. H.264/MPEG-4 A high-compression video format established by international standard organizations ISO-IEC and ITU-T and developed by the Joint Video Team (JVT). This codec is capable of providing good video quality at low bit rates. Appendixes 157

EV Compensation
All the combinations of the camera’s shutter speed and lens aperture that result in
the same exposure.
EV (Exposure Value)
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).
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.
H.264/MPEG-4
A high-compression video format established by international standard
organizations ISO-IEC and ITU-T and developed by the Joint Video Team (JVT). This
codec is capable of providing good video quality at low bit rates.
