A few weeks ago Karl Taylor released a video discussing parabolic softboxes and the gist was that they're pure marketing. While I agree most parabolic softboxes are indeed not true parabolics, I believe them to have a purpose in producing a more narrow spread of light. In this video, I run some tests to see if there's any difference whatsoever when it comes to deep parabolics and regular octaboxes.
