Recently, photographer Chris Hornbecker celebrated the one-year anniversary of the start of his personal project: 1 Millimeter a Day. For every day of 2008, this professional photographer — whose work you’ve seen in ads for Nike, W+K, and EA — shot an image with a focal length that was one millimeter longer than the one he shot the day before. Most of Hornbecker’s photographs, which began at 14mm, within this project were taken outdoors and play with light and perspective. One of our favorites is a sensual, layered, black-and-white image or the rain. Hornbecker will finish his project when his lens reaches its maximum adjustment at 400mm on the 22nd. We’re eager to find out what he’s got planned next.
