Tricks That Enable You to Take Secret Pictures
TRICKS used by press photographers and detectives come in handy when it is desired to snap imposed photographs of friends or members of the family. For such pictures photographers usually use tiny, easily concealed cameras. Despite their size, these midget cameras are surprisingly fast and accurate, and their wide angle lenses make the use of a range finder unnecessary. One of the commoner ways of screening a camera from the intended subject is to cover it with a handkerchief until the trigger is released. Occasionally the camera is carried in a vest pocket with the lens shielded by the wearer’s coat.
New “Camera” Makes X-Ray Movies
MOTION pictures made with a rapid-fire X-ray “camera” devised by a Belgian radiologist will help physicians to study and to diagnose the ailments of moving body organs. Instead of making single shots, the machine exposes a series of large X-ray films in quick succession. This is done by mounting the specially slotted films upon a motor-driven revolving drum, seen within the machine in the right-hand view above. For examination, the resulting sheaf of pictures may then be transferred to motion-picture film and run off in a projector at any desired speed, so that the movements of the internal organs, as they appear on the film, are vividly shown on a conventional screen.
PURSE CONCEALS CAMERA FOR SECRET SNAPSHOTS
Hidden within a bronze holder attached near the clasp of a woman’s purse, a tiny “candid camera” may be operated secretly to snap unposed photographs while the purse is held unobtrusively in the lap or against the body. For less furtive shots, the purse can be held at eye level and the camera trained on the subject through a small, collapsible view finder. Equipped with a high-speed lens, the instrument uses standard thirty-five-millimeter movie-camera film.
SELF-LIGHTING CAMERA NOW USED IN MOVIES
A movie camera that produces its own light is a recent innovation in a Hollywood, Calif., studio. It carries a detachable lamp with a 500-watt tubular frosted bulb upon a bracket at the front. In this way a continuous light is thrown on the face of an actress while the camera is moved around her for a close-up.
Portable Darkroom Worn as Hood Aids Traveling Photographers
When regular darkroom facilities are not available, photographers may have a practical substitute in a portable one in the form of a close-fitting piece of rubber material that slips over the head like a hood. It contains a square of ruby glass for developing and changing plates, etc. At the bottom, it fits tightly to the body so that no light is admitted, but its folds are loose enough to permit ample freedom for the arms and hands. It can be quickly wrapped into a compact package and fits in a small space in the camera case.
Tiny Camera Is Built under Lens with Jewelers’ Tools
Requiring the use of jewelers’ tools and magnifying glasses in its construction, a miniature camera with parts that work, and less than an inch in length, has been made for the royal doll house of the queen of England. Three months’ continuous work by experts was necessary to complete the tiny instrument. All pieces were formed by hand and carefully checked with larger cameras to insure accurate shape.

Strange Scenes from Life Caught with X-Ray Camera
X-ray photography, widely used in medicine and industry, is familiar to almost everyone in its ordinary applications. Recently a German physician has busied himself making X-rays of everyday scenes. Pictures on this page show the result of his hobby. Above, the hand of a sculptress modelling the clay figure of a llama. Note that the wire framework on which figure is built up is seen as white lines
POCKET STEREOSCOPE SHOWS VIEWS ON FILM
Gone is the old-fashioned parlor stereoscope of a generation ago, but its counterpart, in modern guise, has just made its appearance. The new pocket-sized form of the instrument, illustrated above, is as small as a pair of opera glasses and uses thirty-five-millimeter motion picture film instead of paper photographs. A shift lever causes the pictures to appear.
Photo Lens Registers Rays Predating Dinosaurs
BELIEVED by its makers to be the fastest in the world, a new astronomical photographic lens has been used at Mount Wilson Observatory in Pasadena, Calif., for taking pictures of light rays which, scientists claim, left distant stars before dinosaurs trod the earth. In conjunction with the 100-inch reflector at Mt. Wilson, the new lens has photographed spectra of nebulae 30,000 times fainter than the faintest star visible to the unaided eye.
Dr. M. L. Humason, who conducted the Mt. Wilson Observatory tests, reported that the speed of the observatory’s spectrograph was doubled through use of the new lens, which has a speed of F. 0.59. Astronomical data placed the nebulae observed by Dr. Humason as being an estimated distance of 80 million light years from the earth. Through use of the new lens, scientists can now observe faint objects which have previously been deemed hopeless from an astronomical viewpoint, according to Dr. Humason.
Turning Out Photographs by the Million
Great Plants in All Parts of the Country Are Developed to Supply Quick Service and Assistance for Army of Amateurs
DEVOTED exclusively to developing films and printing pictures for an army of amateur camera enthusiasts, great plants have been built up in all parts of the country. During the “busy” months of June, July, August and September, when the weather is best suited to taking pictures, the seven largest finishing plants in Chicago handle more than 114,000 pictures daily. Several have an output of 8,000 to 12,000 every twenty-four hours, and many print more than 5,000,000 as an annual average.
In Cincinnati, a single company serves almost a hundred drug stores, employing a fleet of automobiles to collect the film and deliver the pictures to the proprietors who have found that the “side line” in film service is a profitable advertisement and brings in potential customers. In one week, one of the collectors for this company brought in 20,000 spools of film and as many as 17,500 prints have been distributed in a single day.
