Ring flash

A ring flash is in photography with a special design of a flash. One (or more ) flash tube (s) is / are arranged in a ring around the front of the lens. A sync cord connects the ring flash with the camera.

Characteristics of the ring flash is the exact ring - frontal and thus shadow-free illumination of the motif without shadowing by the lens. Its spatial extension produces a soft compared with normal clip-on light.

On shiny surfaces (as well as eye ) of the ring forms an annular flash reflection which is disturbing in certain circumstances. The lack of spatial effect can cause problems in individual motifs. Here is a partial Abschattieren the flash makes sense or the use of another means of lighting is necessary might.

The ring flash can be used, for example:

• In macro photography and technical or medical documentation and
• In portrait photography.

In addition to the classic ring flash design as variation of the electronic flash, there are also few types with multiple light-emitting diodes (LEDs) as a duration of illumination. They also provide shadow-free illumination, however, are somewhat uneven in illumination. Also improvised continuous illumination of annular tubes are sometimes used.

Another variation of the ring flash is mounted on a lens on the housing or on a rail -purpose geometric combination of small regular flashes or lights. Compared with the ring flash these commercially available or self- composable combination is coordinated voluminous and in individual cases also more complex.
