Appendixes 98GlossaryEV CompensationThis feature allows you to quickly adjust the exposure value measuredby the camera, in limited increments, to improve the exposure of yourphotos. Set the EV compensation to -1.0 EV to adjust the value onestep 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 createdby the Japan Electronic Industries Development Association (JEIDA).ExposureThe amount of light allowed to reach the camera’s sensor. Exposure iscontrolled by a combination of the shutter speed, the aperture value,and ISO sensitivity.FlashA speed light that helps to create adequate exposure in low-lightconditions.Focal lengthThe distance from the middle of the lens to its focal point (inmillimeters). Longer focal lengths result in narrower angles of view andthe subject is magnified. Shorter focal lengths result in wider angles ofview.Image sensorThe physical part of a digital camera that contains a photosite for eachpixel in the image. Each photosite records the brightness of the lightthat strikes it during an exposure. Common sensor types are CCD(Charge-coupled Device) and CMOS (Complementary Metal OxideSemiconductor).ISO sensitivityThe sensitivity of the camera to light, based on the equivalent filmspeed used in a film camera. At higher ISO sensitivity settings, thecamera uses a higher shutter speed, which can reduce blur caused bycamera shake and low light. However, images with high sensitivity aremore susceptible to noise.JPEG (Joint Photographic Experts Group)A lossy method of compression for digital images. JPEG images arecompressed to reduce their overall file size with minimal deterioration ofthe image resolution.LCD (Liquid Crystal Display)A visual display commonly used in consumer electronics. This displayneeds a separate backlight, such as CCFL or LED, to reproducecolors.MacroThis feature allows you to capture close-up photos of very smallobjects. When using the macro feature, the camera can maintain asharp focus on small objects at a near life-size ratio (1:1).
