From the standpoint of the camera, they are perfect for action. But to get back to photography. How to make the most of opportunities presented by motorcycles? The first requirement is a small camera of the miniature type. There can be no question as to the superiority of this type of outfit. First, because of its small size, it is easily carried in a jacket pocket which, when riding a motorcycle, leaves the hands entirely free and occupies no space to speak of. Or again, it is easily tucked into one of the saddle-bags which a great many riders carry on the rear mud-guard of their mounts. Second, it offers speed in operation. In speed work, of the type under consideration, it often becomes necessary to make a series of sequence exposures in rapid succession — for things happen mighty fast at times where motorcycles are involved. One of the most practical aids in this direction is the rapid winder attachment which is made for the Leica camera only. By simply pulling a thin, steel cable on a ring, this camera is automatically set for the next exposure — as fast as you can pull that cable, so the intervals of time between exposures can be gauged. The quicker the camera can be operated, the better. Third, because nothing but a speedy shutter will hold these "popping demons," a shutter speed of 1 / 1 000th is highly desirable, nay, necessary. Small cameras of the Leica type are equipped with such shutters and also fast lenses by means of which full exposures can be insured at high speeds even under unfavorable lighting conditions. So from all standpoints, the miniature camera cannot be reasonably ignored. A few laws of photography come into play when we attempt photographing speeding motorcycles. The old law of photographing objects at an angle rather than directly broadside, coming across the field of view broadside at a high shutter speed, and at a distance, the chances are that the results will be disappointing. The motorcycle will appear lifeless, and in some cases may even show the wheels oval-shaped instead of round. Some may prefer this distortion, claiming that it injects the spirit of speed into the picture. This is so, of course, but most people are after an accurate record of the object rather than a pictorial or realistic interpretation of it. It naturally all depends upon the ideas of the photographer. The lens should be aimed at the object so as to show it either coming towards, or going away from the camera. This angle usually produces best results from a technical as well as pictorial standpoint. Camera angles should be carefully watched, for they play a most important part in the photography of motorcycles. A low "worm's-eye" view is often desirable, showing the cloud flecked sky in strong contrast as the upper background of the picture. Wonderful ideas can be worked out around ihis suggestion, and with the aid of the Wratten G or 23-A, the cameraist should get resuhs which are far above the average. In many cases it will be found impossible to approach the machines and riders sufficiently to secure reasonably large images on the film. From the standpoint of safety, too, it is usually desirable to be a short distance away from the actual field of activity. Particularly is this important in the case of hill-climbs where the best camera position is at or near the top or finish— it is here where the best action takes place — and also the wild buckings and spills. A telephoto lens would be the natural selection, and most workers therefore, use such lenses. Given a reasonably bright sun, a telephoto lens with a speed of f:4.5, speed film, and a quick eye, successful shots can be expected at from l/500th to 1/1 000th second exposures. The telephoto lens, aside from serving a practical purpose, also produces a more "plastic" effect which is entirely pleasing on shots in which powerful action of this nature is back-lighted and dustladen. It seems a pity that motorcycling has lain dormant in the public's mind for so long, for it is an ideal sport, comparable in every respect with horseback riding. As it offers such marvelous photographic opportunities, it should be more thought of by amateur cameraists in general. The comparative rarity of the machine makes it even more desirable for photographic purposes, for the photographer can produce pictures which stand apart from the usual run of action photos.
