Octabox
An eight-sided softbox whose near-circular shape produces round catchlights and even wrap-around light.
Measured in
cm
In depth
The octagonal shape approximates the sun and other natural round sources, so the light and its reflection in the eye look convincing rather than obviously manufactured. Large octaboxes of 120 cm or more are the standard key for beauty and fashion work because they wrap around the face without the hard corners a rectangular box reflects.
Examples in practice
A 150 cm octabox placed directly above and in front of the model gives soft, even light with a single round catchlight.
