Even if you know nothing about camera work, you probably know what lens flare is, especially if you’re a Star Trek fan. Essentially it’s the light bouncing off the lens, and there’s nobody who’s used it more than JJ Abrams, to the point where there was even a parody on YouTube called Lens Flare the Movie.
Abrams confirmed to Crave that he “actually had to use ILM [Industrial Light & Magic] to remove lens flare in a couple of shots, which is, I know, moronic. But I think admitting you're an addict is the first step towards recovery."
Of course, the big question is, will there be lens flare in Star Wars? We’re actually guessing there won’t be, because it would take the movie out of the Star Wars universe, so to speak. As much as Abrams has his own style as a storyteller, and lens flare is one of his trademarks, he’ll probably want to keep the look of Star Wars more traditional, and not too much of a departure from its norm.
