Ring-flashing variety

Common ring flashlights are mainly divided into three types: connected type, separated type and extended type, as shown in the above figure.

This kind of ring flash is a high-power continuous ring flash, and the shooting effect is the best among all kinds. It can effectively eliminate shadows, but it is more expensive.

This kind of ring flash is a single ring flash, and its erasing performance is not as good as that of continuous flash. However, because the position of the flash can be placed freely, the freedom of creation is very high. The disadvantage is that the power is lower than that of continuous flash. Mainly used for macro photography.

Because ring flash is generally expensive, it is popular now. A light guide rail similar to that shown in the figure is installed on the ordinary flash lamp, so that the flash lamp emits light in a ring shape and produces the effect of ring flash. Disadvantages are large volume and low flash uniformity.

Ring flash can be used with other lights, and the effect is very good.
