Photograph of Tim Jenison via Boing Boing It has long been suspected that some of the old masters may have relied on optical devices such as the camera lucida to help with scale and proportion in their paintings, leading to more lifelike interpretations of landscapes and portraits. Tim Jenison, a Texas-based inventor and computer graphics specialist, became obsessed with one such painter: Dutch master Johannes Vermeer, who created such realistic paintings that they seemed to have more in common with photography than paint. Could Vermeer have created a system for replicating scenes in front of him using lenses and mirrors? Jenison embarked on an experiment to recreate one of Vermeer’s most famous paintings, The Music Lesson. It’s an obsession that would consume five years of his life involving the actual construction of the entire room seen in the painting down to the most minute details, the (re)invention of a 17-century optical technology using period-appropriate tools and materials, and then seven months spent painting. The entire endeavor was filmed and turned into a documentary titled Tim’s Vermeer, the trailer of which you can see above. The film began its theatrical run in January, but just became available as a Blu-ray combo pack and digital download today. Jenison also wrote a detailed article about the entire step-by-step process that was published yesterday on Boing Boing.
