Matrix Metering system Rear-Curtain Sync Release-Priority for autofocus Single Servo AF Slow Sync Vignetting White balance An advanced exposure metering system using a multi-segment sensor and computer. Flash fires an instant before the second (rear) curtain of the focal plane shutter begins to move. When slow shutter speeds are used, this feature can create a blur effect from the ambient light, i.e., a flowing-light pattern following a moving subject with subject movement frozen at the end of the light flow. See also "Front-Curtain Sync." Shutter can be released anytime (i.e., even when subject is not in focus). Helps you avoid missed opportunities when you are not concerned with absolute focusing precision. Once the subject is in focus, focus is locked. Useful for recomposing the picture. Release-Priority is given to Continuous Servo AF mode while Focus-Priority is given to Single Servo AF. Using Custom Setting, however, you can change the priority to Focus-Priority Continuous Servo AF or Release-Priority Single Servo AF. A flash technique for using the flash at a slow shutter speed. Flash shooting in dim light or at night at a fast shutter speed often results in a flash-illuminated subject against a dark background. Using a slower shutter speed with the flash brings out the background details in the picture. Use of a slow shutter speed with Rear-Curtain Sync is particularly effective for illustrating the movement of a stream of light. Slow Sync mode extends the automatically controlled shutter speed range (in Programmed Auto and Aperture-Priority Auto) down to 30 seconds. Progressively diminished illumination on the image from the center to the corners. There are two kinds of vignetting-natural vignetting caused by the lens, and vignetting that is caused by improper use of accessories such as a lens hood or filter. Provides adjustments to match the type of lighting used to capture an image. Glossary-4 April 29, 2004
