Strobe flash

from Wikipedia, the free encyclopedia

In photography, a stroboscopic flash or serial flash is a special stroboscope that emits short flashes of light in quick succession.

With stroboscopic photography it is possible, for example, to combine the individual phases of a rapid movement in a single shot . A black background is not absolutely necessary, but recommended, as the individual images can be combined particularly well here.

Computer flash units with a stroboscope function usually work with greatly reduced power in multiple flash mode . H. shortened burn time .

The suitable minimum shutter speed is calculated using the formula:

Shutter speed = number of flashes: frequency

Example: For four flashes with a flash frequency of 5 Hz, 4: 5 = 0.8 seconds applies, so an exposure time of one second is set on the camera .
