The invention relates to a method of photographing a desired object with a panoramic X-ray apparatus fitted with automatic exposure, comprising an X-ray generator (4, 5), an X-ray tube (5) and a film (7) with its holder. In the method, the detection of a cone of rays (9) penetrated through an object is effected before the actual filming is started and, after the detection, the filming is effected by using a cone of rays (6), directed so as to bypass a detector (1).
