>>3499265Cinestill is a company that converts movie film, into a photographic film that can be processed with C-41 chemicals. As a result, you get a film that gives you colors you'd usually found on movies recorded with film and most notably a cool flaring effect around bright light sources.
They currently offer 2 color negative films: Cinestill 50D which is daylight balanced and pretty slow, and Cinestill 800T which is tungsten-balanced (balanced for indoor tungsten lighting) and fast; perfect for night photography and probably the one the other anon wants you to get.

They tend to go out of stock really fast and for a while so be aware of next production runs.
