Ringlight

Figures 2 and 6 are of the same specimens but photographed with a ringlight.

Until recently, ringlights have been chiefly associated with technical illustration, such as close-up photography in medicine and dentistry.

Built-in ringlight flash provides virtually shadowless, wraparound illumination for inaccessible or elusive subjects.

One of the characteristics of ringlight, when used as the only source, is its shadow. Because the light expands equally in all directions, it also throws an even shadow.

I had created a faux-ring light, and I was able to get a very cool ringlight effect for very little money.

The planet is illuminated by a superb ringlight, in addition to the radiance of various moons—for of the satellites there are several always above the horizon at the same moment.

Gray striations became visible on the planetary surface, illuminated by ringlight.

The superbly designed hills already were taking on the blackness of coming night, several glaring in the ringlight as usual, those towards the horizon fading off into a jet obscurity.
