Harness smoothing, shadowless light and beautiful catchlights
Not an accessory as such, but a different kind of light altogether. A ring light is simply a circular ring of light that provides frontal illumination with minimal shadows. You direct your lens through the circle, so the light comes from the camera position. It’s similar in some ways to the light from a pop-up flash, but it’s far more attractive as you don’t get the hard shadows pop-ups inevitably produce. Instead, you get beautiful, shadowless illumination, which is very kind to faces, and useful if you want to soften wrinkles. The other benefit is the attractive ring-shaped catchlights you’ll get in the eyes.
