When would you recommend using LC filters?
I'm gearing up for a short film in January and the main reference the directors have given me is "Five Easy Pieces." It appears that that film could've been shot with LC filters, but I'm not sure. I'm hoping to use LC as a creative choice rather than technical — how powerful is the effect of an LC filter, and what grade of LC would you recommend (1/4, 1, 2,3,4 etc)? This film is a lot of EXT. DAY.
