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.
Image sensor
The physical part of a digital camera that contains a photosite for each pixel in
the image. Each photosite records the brightness of the light that strikes it during
an exposure. Common sensor types are CCD (Charge-coupled Device) and CMOS
(Complementary Metal Oxide Semiconductor).
ISO sensitivity
The sensitivity of the camera to light, based on the equivalent film speed used in
a film camera. At higher ISO sensitivity settings, the camera uses a higher shutter
speed, which can reduce blur caused by camera shake and low light. However,
images with high sensitivity are more susceptible to noise.
