Glossary 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). 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. JPEG (Joint Photographic Experts Group) A lossy method of compression for digital images. JPEG images are compressed to reduce their overall file size with minimal deterioration of the image resolution. LCD (Liquid Crystal Display) A visual display commonly used in consumer electronics. This display needs a separate backlight, such as CCFL or LED, to reproduce colors. Macro This feature allows you to capture close-up photos of very small objects. When using the macro feature, the camera can maintain a sharp focus on small objects at a near life-size ratio (1:1). Appendixes 98

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).
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.

The physical part of a digital camera that contains a photosite for each

that strikes it during an exposure. Common sensor types are CCD
