All scenes were shot around Philadelphia using my full-spectrum digital camera and a yellow filter. A full spectrum camera is a camera that has had it's IR blocking filter removed, allowing the camera to see into the infrared. The yellow filter blocks all visible light up to yellow and allows infrared to pass through. The first scene and time-lapse title was prompted by an infrared series that I’ve been shooting over the years called “Wonderland”.
