Strobe function of flash lamp

Most people use flashlights to supplement the lack of light. However, in the field of professional photography, flash is more widely used, and the expansion of flash function provides photographers with more creative means. You may have seen such photos: the beautiful crown splashed at the moment when the milk fell, the moment when the bullet passed through the playing cards ... these images that are difficult to see with the naked eye are captured and recorded by modern scientific and technological means.

Strobe is one of the special functions of modern flash. Usually, the flash is triggered only once, but when shooting a moving object, the flash will be set artificially to make it multiflash during one exposure, which is called "stroboscopic". If you want to get the effect of the photos in the article, you should use a flash with stroboscopic function to make a series of continuous moving images appear on the same screen.

When setting different strobe times or outputting single light with different values, the flash index will change greatly. The basic technical essentials of shooting are as follows:

1. Because the shutter of the camera is open during the whole shooting process, a dark background and shooting environment should be adopted, and a stable tripod should be used.

2. Strobe can only record one image at a time. It is necessary to plan the moving speed of the subject and the number of sheets required for a single negative in advance, and set the appropriate strobe and interval more accurately on this basis.

3. Stroboscopic photography requires the subject to stay away from the background to prevent light and shadow from appearing in the picture. The camera is closer to the subject, because the flash index will drop greatly after setting the flash. There are many different technical requirements for different cameras in real shooting. The selected pictures are stroboscopic photography used in foreign sports photography. This creative method successfully decomposes the athletes' movements and provides a more vivid scientific means for observation and research.
