Retardation level of light is indicated by the number f, or relative aperture. The lower the f number, the greater the smaller the opening or penghalangannya level. Aperture diaphragm is controlled by the window. Relative aperture is set by a diaphragm. For SLR cameras, lenses, aperture diaphragm is equipped with a regulator that regulates the amount of light entering a photographer as you wish.
Lens type faster or slower lens is determined by the range of F that can be used.
In addition to normal lens, wide angle lens is also known (wide lens), small angle lens (telephoto lens), and variable lens (variable lens, or by the laity is called the zoom lens.
Wide-angle lens has a focal length that is smaller than normal lens. But it depends on the designation used by the film width. For 35 millimeter film, lens 35 millimeters wide angle lens will be called, while the 135-millimeter lens will be called a telephoto lens.
Variable lens distance can be altered to focus, by changing the relative position of the lens elements. The lens will focus light so that the resulting image to fit the movie. Grouped according to length of the lens focal length (distance between the two lenses).
Focal length affects the composition of the image that is able to produce. In the general population, better known as zoom.
[Edit] Portraits lighters
Lighters portrait or shutter button is fitted behind the lens or between the lenses. Most SLR cameras have a timer mechanism to allow varying the shutter opening time. This time is short shutter is opened, allowing the beam of light on film.
Some ordinary people consider the ability of the camera equal to the maximum shutter speed that can be used.
