My personal experience with all sorts of lighting is ~15 years working in the commercial & editorial photo world in NYC. I’ve handled a bunch of parabolic mods, including Broncolor & Briese.
Commercial or not, and putting aside whatever shade you’re trying to create repeatedly using Chinese as a pejorative… the results speak for themselves. Anyone who knows what they’re looking at can see the quality of light shared in the video. If it’s not for you, I’m not offended… but if we’re chatting about “the parabolic look”, Selens seems to deliver.
On this whole idea that a parabolic “doesn’t have a look” - sure, you can make it emulate a very overpriced octa, or a very overpriced ringflash-ish… but if you’re looking to have it behave in a way that no other single modifier can, that’s “the parabolic look.”
