Abstract
IN ” A Note on Stereoscopic Photography”1 Dr. John R. Baker refers to different methods of making stereoscopic photographs of near objects. There are two possibilities: the axes of the cameras can be parallel to each other, or they can be convergent to the object. Dr. Baker concludes: ” The convergent camera gives the proper representation of the object”. I think this conclusion is not right. Let us consider a moment a photograph made by a camera in an arbitrary position. It always represents reality if we look at it in the right manner. It is necessary to put the eye in the place occupied by the lens in making the photograph, and the different points of the image will be seen under the same angles as the corresponding points of the object. In Fig. 1 of Dr. Baker's article both photographs have to be seen from D and so A and A, B and B, and C and C are seen in the same direction.
