John Chiara is one of those photographers whose approach and craft is truly humbling in its creativity and scale. Based in California, John shoots one image a day using his home-built, larger-than-life, pinhole-style film camera that he has rigged to a trailer.

John truly takes the idea of “getting behind the lens” to a new level, as he must literally climb inside of the camera to load it with a giant sheet of paper coated with light-sensitive chemicals (he then exits the camera through a long tunnel that appears to be made out of garbage bags). John admits that his technique is somewhat primitive and that he doesn’t use modern light meters or even a stopwatch to make his exposures—everything is based off of intuition—but the result is absolutely breath-taking.
