ABSTRACT:
A radiation source, inclined relative to an optical axis of a camera, is used for directing light towards a reflecting surface and thence towards a subject to be photographed. A sensor detects light from the radiation source which is reflected from the subject. A determination is made as to whether the intensity of light from the radiation source which is reflected from the subject is below a predetermined level. A light source is provided which is inclined substantially the same as the radiation source. The light source is utilized for visibly illuminating the subject by directing visible light towards the reflecting surface and thence towards the subject. When it is determined that the intensity of light from the radiation source which is reflected from the subject is below the predetermined level, an indication is provided to a camera operator that the light source cannot adequately illuminate the subject.
