The photography. of moving objects is a study in itself; in cinematography blur does not show because the eye does not perceive details when objects are in rapid motion. But in still photographs we naturally expect to sce the motion cut sharp. The tables' of shutter-speeds required to stop various movement are interesting but apt to mislead the amateur as they do not sufficiently stress the point that at many of those shutter-speeds it is highly improbable the film" will receive enough exposure to give a printable negative.
'The rule for photographing moving objects is.... estimate the shortest exposure "which promises reasonable hope of a printable negative and give that exposure, trusting to judgment. and luck' successfully to "stop" the motion. Use the largest aperture of the lens, of course, and focus in_advanee' on the position you expect the moving object to reach when you wish to it, Note that if it, requires exposure to stop the motion of an object passing at right angles, two-thirds will suffice if it is passing at oblique angles and one-third if it is coming nearly towards the camera (in practice even less). The amateur is therefore recommended to choose the latter position. It is perfectly easy to "stop" the motion of an or: train 100 feet distant with low an exposure as 1/50th second if it is coming towards you where-ax about 1/300th is required if it is passing at right angles. The same thing applies to all races. For athletics try to get the sub-Jects against the sky, avoiding ark backgrounds as this makes: the best of slight under-exposure. Real speed-photography req special equipment and is beyond, the scope of this article, How to Manage Waves.
Wave and water photography' must be done slowly, not fast, as water is usually in motion and a high shutter-speed "freezes" all effect of motion. 1/30th of a second or thereabouts (in good light use stop F 16, U.S. 16) is just right. Slower it' is a blur and faster all sense of motion is lost. Beaut jo and wave pie-tures can be made by photography and this tip will help very considerably.
all speed-work foresee the position you want and press the Telease just before you want the picture, thus allowing for the lag. of the fingers and shutter; other-ise you may find you just missed
