If we are talking about the same size. The softness of light is
harder <Adding the size, beauty dish is usually less than 28", while this soft box
is 50". I can pull this softbox pretty far away and still getting soft light
. It means I can use it for full body, or even small group photo. Beauty
dish is usually for head shot.
Another thing the is shape of catch light in the eyes. Beauty dish will give
you a circle shape.
