Mini DV Cassette Stands for Mini Digital Video Cassette. A filter that absorbs some of the light passing through the camera lens. The degree to which an image is distinct in its details as a function of the spacing of individual optical elements, such as the grain of a light sensitive emulsion. High resolution Films have a greater number of lines per millimeter. The calibrated length of time of exposure.
Shutter speed controls the amount of light that reaches the film during exposure.
Like the aperture it is a variable that is controlled either mechanically by the photographer or electronically by the camera itself. A feedback mechanism in the camera that controls the auto focus function. Specifically, in single servo A.F. mode the camera focuses on a still object and locks the focus on that object when the shutter release button is depressed half way. In continuous servo A.F., the camera focuses continuously when the shutter release button is depressed half way. In this mode the camera's auto focus mechanism tracks anything moving in the frame.
