 located in the camera. Unfortunately, such an approach might fail. Specifically, while, the lens aperture size specifies the amount of light that instantaneously strikes the film, this size also defines the so-called depth-of-field in the resulting photographed image, i.e. a range of minimum to maximum camera-to-subject distances in which objects located therein will be perceived in the image as being sharp and in-focus. As the aperture size of a given lens increases, i.e. the lens is opened and its so-called "f" number decreases, which ordinarily occurs in low light conditions, the depth-of-field produced by that lens correspondingly decreases. Accordingly, with certain subject thicknesses, the depth-of-field that results from a maximum lens aperture exposure may be too restricted to fully cover the entire subject. Thus, portions of the subject located at camera-to-subject distances that are outside the range specified by the depth-of-field for the given lens aperture, i.e. too close to or too far from the camera, will appear out-of-focus in the resulting photographed image. Therefore, in order to provide an appropriate depth-of-field to cover the entire subject, a smaller lens aperture than the maximum available size must be used along with a slower shutter speed to generate a sufficient exposure. Unfortunately, a photographer is often unable to steadily hold a hand-held camera for times typically in excess of, for example, 1/50th of a second for a 50 mm lens. Hence, as the shutter remains open for increasingly longer periods of time, the camera becomes increasingly sensitive to camera shake or subject motion which, when it occurs, blurs and ruins the entire picture. Therefore, to reduce the incidence of noticeable image blur, particularly resulting from camera shake, shutter speeds equal to or slower than of 1/50th second for use with a 50 mm lens should be avoided for use in a hand-held camera. Consequently, other techniques, such as mounting the camera on a tripod or using an auxiliary light source, e.g. a so-called flash unit, or higher speed film, i.e. a more sensitive film, are often required in order to provide acceptable combinations of lens aperture openings and shutter speeds in low light conditions. Unfortunately, a flash unit or a tripod may not be currently available. Also, films that are increasingly sensitive tend to produce pictures that exhibit increasing graininess, thereby adversely impacting the quality of the picture. With this scenario and in

Specifically, while, the lens aperture size specifies the sum of inner light that instantaneously strikes the film, this size also define the so - called astuteness - of - field in the resulting photographed image, i.e. a scope of minimum to maximum camera - to - national distances in which objects locate therein will be perceived in the image as being sharp and in - focus. As the aperture size of a given lens addition, i.e. the lens is opened and its so - called " f " issue decreases, which ordinarily occurs in low unaccented conditions, the depth - of - field produced by that lens correspondingly decreases. consequently, with certain subject thicknesses, the depth - of - field that results from a maximal lens aperture vulnerability may be too restricted to fully cover the entire subject. Thus, portions of the subject locate at camera - to - subject distance that are outside the stove specified by the depth - of - discipline for the give lens aperture, i.e. too close to or excessively far from the camera, will appear out - of - focus in the resulting photographed image. Therefore, in decree to provide an appropriate depth - of - field to cover the entire subject, a little lens aperture than the maximal available size must be used along with a slower shutter speed to generate a sufficient exposure. Unfortunately, a photographer is often unable to steadily hold a bridge player - held camera for times typically in excess of, for exercise, 1/50th of a second for a 50 millimeter lens. Hence, as the shutter remains open for increasingly longer periods of clock time, the camera become increasingly sensitive to television camera shake or subject motion which, when it occur, blur and ruins the entire picture. consequently, to reduce the incidence of noticeable image blur, particularly result from camera shake, shutter speeds adequate to or slower than of 1/50th second for use with a 50 mm lens should be avoided for use in a hand - hold camera. Consequently, other techniques, such as mounting the camera on a tripod or use an accessory light source, e.g. a so - called flash unit, or higher focal ratio film, i.e. a more sensitive film, are much required in order to provide acceptable combinations of lens aperture orifice and shutter speeds in low light conditions. Unfortunately, a flash unit or a tripod may not be presently available.
