CSW! It is interesting you say you don't want to pursue MMA but you are talking about mixing your martial arts. :) Maybe you mean you don't want to fight in a cage for money?
Note that the gold reflector will shift the colour temperature of everything it hits, so if you're photographing a model wearing white, and that white has to look white in the final picture, you're just going to have to put things back the way they were in post anyway
Parabolic reflector. A parabolic (or paraboloid or paraboloidal) reflector (or dish or mirror) is a reflective surface used to collect or project energy such as light, sound, or radio waves. Its shape is part of a circular paraboloid, that is, the surface generated by a parabola revolving around its axis.
