The characteristic of the ring flash light is the exactly ring-shaped frontal and therefore shadow-free illumination of the subject without shading by the lens. Its spatial expansion creates a soft light compared to normal plug-on flashes.

The lack of spatial effect can also cause problems with individual motifs. Here is u. It may make sense to partially shade the flash or use a different light source.

In addition to the classic ring flash design as a variant of the electronic flash, there are also isolated designs with multiple light-emitting diodes (LEDs) as permanent lighting . They also offer shadow-free lighting, but are somewhat more uneven when it comes to lighting. Improvised permanent lights made of ring-shaped fluorescent tubes are sometimes used.

Another variant of the ring flash is a geometric combination of small regular flashes or lamps that can be mounted on the lens, on the housing or on a rail.
