As a visually-inspired, inspiration-hungry person, I cycle through various obsessions on a pretty regular basis. The latest of these is Cyanotypes, a photographic process that results in a cyan blue print. Blue is one of my favorite colors, so the combination of vintage photographs and this rich blue color is pretty tough for me to resist. A little searching led me to the Cyanotype Flickr Pool, where you can find thousands of examples, including the select few below (click on each image to get to the original source).
