Read full description

Discover and capture the ethereal beauty of trichromatic photography with this one of a kind camera app. Trichromy is the process of creating color images by combining 3 monochromatic images: typically red, blue, green. Because the exposures are taken at separate times, they layer in ways that range from subtle shimmers to utterly psychedelic. This app features a beautiful, straightforward interface that lets you experiment with trichromatic photography on your phone, no fancy equipment or complicated workflow required!  Use the main shutter to capture three successive exposures with a delay, which you can change with the slider. Or use the individual colored shutters to capture channels in any order and timing you want. This method of producing color images goes back to the 19th century and was one of the earliest. Notably, Sergey Prokudin-Gorsky used the trichromic process to document large swaths of early 20th century Russia.
