The difference between octagonal light box and quadrilateral light box

The difference between octagonal light box and quadrilateral light box;

1, octagon: the scattering area accounts for a small proportion of the circle, and it has a certain light gathering effect, but it is not particularly obvious, especially when shooting parts (makeup, small still life). I don't use this much, but I use it together most of the time (ashamed). For example, add a layer of soft light cloth inside to reduce its soft light intensity and create a layered feeling with other lights (for example, when shooting clothing details).

2. Rectangular soft light box (four corners): This kind of soft light box is most commonly used in daily shooting, with a general scattering area, but the combination of various lights is the most playful.
