Abstract
The device and method are intended for the standardization of picture taking without contact with the subject. Two light beamers converging at a distance within the range of camera focus are enabling reproducible viewing conditions via superimposition of the spots of the beamers on the subject and the light of the beamers are extinguished during picture taking in order not to bias the image. The device is constituted of a body (1) adaptable to a camera (1) with objective (2) and is including two light beamers (4A) and (4B) whose beams (5A) and (5B) are converging at a distance (D) within the focus range of the camera as well as a mechanism to extinguish the light beamers during picture taking. It can be improved by enabling the covering of the focus ring (2) and zoom ring (8) of camera (1).
