Typically a ring flash is about 4 inches across and it easily fits around the camera’s lens. Well, this is no ordinary ring flash. This DIY flash is completely scalable so it can actually fit around the object to be photographed, even a person!
The Ring Flash / Ring Light is a unique light source since it gives you a hard light but because the light comes from all around the lens the only shadow is a darkened halo around a subject, but the subject it self is uniformly lit.
