![]() What is behind that diffusion isn’t that important as long as it spreads the light uniformly around. ![]() Don’t get me wrong parabolic reflectors are brilliant reflectors for collimating light and bron make the best but all the properties of them are lost as soon as you put heavy diffusion in front, the light is no longer collimated it is simply diffused with a central hotspot on the Staro. The parabolic design of the Staro in my opinion is largely pointless and has been put there for aesthetic reasons and is likely a leftover part from the satellite evolution which they no longer make. I disagree, a simple giraffe boom and it would take a couple of minutesģ. A simple box of black polyboards around your model or black velvet would also solve the issue.Ģ. If everything is far away or black then it’s not causing you any problems as there is no uncontrolled light to infiltrate the shadows. You can reduce light spill on the scrim by using a P70 but remember light spill is only a problem if there are white walls and ceilings. The perpex normally should be already able to soften and hide the internal light box shape, but evidently, on this size, it’s not so.ġ. Broncolor published some video about Staro, but they are not made by you… hence they are quite superficial.Īnyway I think that a scrim with a bare bulb has some difference:ġ-The scrim has the problem of the light spill around and does not allow to mount a grid to control the light cone in the frontģ – keeping perpendicular the light respect to the scrim can be difficultĢ- Broncolor designed the Staro soft box using a parabolic shape with a specific curvature and a specific focus point (placed outside the panel): is it just marketing ? Making a simple ray tracing simulation of the reflected light inside the parabolic box, I noticed that with this geometric design, the light is reflected from the parabola to hit uniformly edge-to-edge the internal face of the diffusion panel. Thanks Karl for the reply and for anticipating the new upcoming video. ![]() In the test, Karl demonstrates three comparisons between these modifiers - with the front and inner diffusion, with only the inner diffusion, and with no diffusion - and the results speak for themselves. Nevertheless, Karl puts one to the test to check the results for myself. ![]() The term ‘parabolic softbox’ is something of a contradiction, and the physics behind these cheap modifiers does not make sense. So how do these two opposite effects work together? Quite simply, they don’t. ![]() Parabolic lights, on the other hand, focus the light and produce sparkly light with more contrast. Softboxes and Octaboxes are designed to produce homogenous lighting, with the inner and front diffusion acting to disperse the light and produce a very even overall result. In this video, Karl does a side-by-side lighting comparison between a 150cm Parabolic Softbox and 150cm Octabox to see the results. When it comes to photography lighting options, parabolic softboxes are often marketed as better than regular softboxes, but more affordable than true parabolic reflectors. ![]()
