The Folmer & Schwing Division of the Eastman Kodak Company manufacture a great variety of photographic instruments used for special scientific work and of little or no interest to the professional photographer. But occasionally such an instrument may have such a wide range of adaptability that, while primarily intended for a very special purpose, it may also be used by the professional photographer to good advantage.

This we think is the case with the F. & S. Finger-Print Camera, which will, without doubt, become a part of the equipment of many professional photographers. It will be used for photographing finger prints, but a number of other uses will be found to come within its range of adaptability.

The finger-print system of identification is in common use and has been found to be a very accurate means of identifying criminals. Most Police Departments keep a finger-print record for identification, and such records are beginning to prove extremely valuable. The Army and Navy also use it as a means of identifying deserters, and the possible application of the system is drawing the attention of various commercial and educational organizations.

Identification by finger prints is based on the practically imperishable and unchangeable design of the ridge formation on the tips of the thumb and fingers, and the fact that each design possesses characteristics which cannot be duplicated.

If the house burglar or safe blower has been careless enough to leave the print of a finger about his work it can readily be photographed with the F. & S. Finger-Print Camera, and if a corresponding finger print is filed among the police records; it is a simple matter to find it and know the man to look for, also to confront him with the evidence of his guilt.

The difficulty of securing good photographs of finger prints has made a special form of camera desirable for this purpose, and since many of the smaller cities do not have a special police photographer the local photographer, may find it to his advantage to become an expert finger print photographer.

The small size of the camera makes it especially convenient to use in confined locations where the ordinary camera and tripod would be useless and artificial illumination of the subject would be difficult.

Aside from its use in criminal investigation the camera may be used for quickly obtaining records of signatures on checks, receipts, passes or legal papers and for photographing details of patterns, designs of materials, trade marks, labels or bits of any printed or written matter not larger than the front opening of the camera, the reproduction it makes being actual size.

As will be seen by our illustration, the camera is so constructed that the front may be pressed firmly against the object on which the finger print has been made, the illumination being furnished by four miniature electric lamps directly inside the front but not in line with the lens.

The lever that opens the shutter, automatically switches on the lights, and as the exposure is completed, switches them off again, but they may be operated independently for locating the object or properly placing the camera over it, by pressing a small button. The lamps are operated by batteries contained within the camera and either lamps or batteries may be renewed at little expense.

The lens is the /.6.3 Kodak Anastigmat, which is unalterably fixed in the camera at a point that renders a full sized image of the finger print or other object with extreme definition. The actual size of the reproduction is 2 1/8 x 3 1/8 and the film, film pack or plate used is 2¼ x 3¼. The size of the camera is 11¾|x6x6 and the weight with batteries is 5 lbs. 8 ounces.

The price of the F. & S. Finger-Print Camera complete with lens, shutter, two batteries, ten lamps and one double plate holder, 2¼x3¼, is $30.00. An illustrated booklet giving a full description and the method of working the Finger-Print Camera will be mailed, on request, by the Folmer & Schwing Division, Rochester, N. Y.
