Instructions for Radex Stereo Parallel
Introduction - With the introduction of color film, photography, as an art and a hobby, entered a new and even more fascinating era. No single development in the past decade has contributed more to the advancement and universal popularity of photography. Only one step now remains to achieve what is truly the "ultimate in photography" -- Full Color in Third Dimension. The Radex Stereo-Parallel was designed to enable you to experience this new phase of color photography with your present camera equipment. Although designed for the popular 35 mm camera, this Parallel can be used with any type of camera. Its operation limits its application to subjects involving little or no motion, but it should be remembered that good stereo cameras for action shots, are still quite expensive.The Stereo-Parallel is merely an economical but accurate device which enables you to shift the position of your camera 2½" between two individual exposures. The resulting two transparencies form a perfect stereo pair which may be viewed or projected in Third Dimension. When Kodachrome or Ansco Color transparencies (35 mm and Bantam "828" size) are processed by the laboratory they are usually returned to the sender mounted in standard 2" x 2" cardboard binders.accommodate two such mounted Stereo "twin" transparencies in the proper position for Third Dimension viewing in the 
or they may be removed individually for flat viewing or projecting.When you view your first Third Dimensional picture in full color, you will agree that this is truly--PHOTOGRAPHY." 1st MOUNTING THE CAMERAThe Stereo-Parallel is to be mounted between the camera and the tripod. The base of the Stereo-Parallel is threaded to fit any standard tripod with a ¼" thread. The camera may be mounted first to the Stereo-Parallel then both to the tripod, or vice versa, whichever is easier for your particular equipment.  When mounting the camera on the Stereo-Parallel, turn the thumb-screw "A" into the camera as far as it will go, then tighten up and secure with knob "B." This procedure will eliminate any possibility of stripping threads as the camera must be tightened securely to the Stereo-Parallel which in turn must be secure to the tripod. [Note: The letters in the above image were modified from the original for clarity. --DJA]After setting up the tripod check the Stereo-Parallel mounting to be sure that the camera is secure. Remember that after your first exposure, the film must be advanced for the second exposure. During this operation and the shifting of the camera from one position to the other, there will be a tendency for the camera to slip unless it is securely tightened to the Parallel.2nd LINING UP AND LEVELINGAfter mounting the camera and Stereo-Parallel on the tripod, set up in the general direction of the subject. Composition in third dimensional photography is of utmost importance. In "framing" your subject always try to have some object, such as a tree, building, or fence in the foreground. This will add dramatic depth to your pictures. Such objects should never be less than ten feet from the camera and should occupy only a small portion of the over-all composition. It is desirable to have the camera as level as possible to the horizon. This can be done by tripod adjustment or by using a tilt-head between the Stereo-Parallel and the tripod. A small hand level placed on the Parallel or the camera will be valuable in "leveling up."Before shooting check your composition and level by shifting the camera from one position to the other.In shooting a third dimensional picture with the Stereo-Parallel both exposures must be the same. Determine the "f" stop and shutter speed as though you were taking a straight picture.  After making the first exposure (1) advance the film, (2) shift the position of the camera, and (3) make the second exposure.In advancing the film between exposures it is best to steady the camera by holding it and the Parallel tightly. When shifting the position of the camera for the second exposure, hold the tripod head in one hand and shift the Parallel with the other, as shown. Do not lift up on the camera itself - shift the Parallel, otherwise you may move the camera slightly out of line.When your film has been processed and a stereo pair mounted in 2" x 2" binders, slip them in a Radex Stereo Slide Holder and view them in a Radex Binocular-Scope. If you do not see depth at first, switch the position of the two slides. Then, providing they were properly taken, you will see dramatic depth in full-color - photography at its best.Points to Remember... 1 - Be sure the camera is mounted securely to the Stereo-Parallel. 2 - Be sure the Stereo-Parallel is mounted securely to the tripod. 3 - Have some object in the foreground to dramatize the depth. 4 - Have the camera level to the horizon. 5 - Steady the camera when advancing film. 6 - In shifting position, lift by the Stereo-Parallel, not the camera. 7 - Use the same "f" stop and shutter speed for both shots of a stereo pair.
