"Prisoners" and its conventions

The lighting in the film "Prisoners" feels very natural. For a majority of the movie, the characters are lit by a light placed outside the window, which creates the illusion of daylight or on one side in the indoor shots as if someone were in the room or building. In some scenes, the only light present comes from headlamps, flashlights, and candles. Here, we see high contrast, low light, and deep shadows while still retaining clean visuals. Prisoners is a dark film in content, and the director really shows it through the way he did the  lighting. The audience doesn't actually see the sun even once throughout the entire film. Every shot outdoors is done at night, or with gloomy weather, and sometimes in rainy or even snowy times, still obscuring the sun. That results in an a very grey tone with desaturated colors and a visual aesthetic which lines up very well with the story. For the indoor shots, the characters are almost always backlit or side lit, which creates silhouettes and some serious contrast. In doing their lighting like this, characters are often mere shadows that move around in the scene. Doing this very well fits the fact that many characters have something to hide, unfolding those things throughout. Any Camera movement in the film is very natural and almost unnoticeable. If it makes sense, the camera work doesn't call any attention to itself. This helps both the audience to stay in the story and to keep them immersed in the world being shown to them. Throughout the film, we see the characters clothed in mostly dark outfits. Even with these dampened colors, the costumes are still very basic, not doing anything extravagant. Nothing extravagant is really needed though, because the conventions don't call for it. Of these conventions, I could realistically stick to most of them. We have no shortage of grey days here in Florida, and the same goes for rain. If anything, thrift stores for costume pieces. In terms of the lighting for indoor scenes, again, it's all totally doable. I have access to floodlights, headlamps and flashlights, I'm Set. In reference to the actual movie, all I ~really~ need to pull it off is a good actor and a mirror to break.
