An old technique has a new lease on life in the digital world of Photoshop to create interesting images from both compact digital cameras and from dSLRs. Back in the dark ages when I shot film I used a creative technique called tri-color photography. In this technique I would set my camera, then a wonderful Canon T90, into multiple exposure mode, mount a Cokin filter holder and then, with the camera on a good tripod, shoot three exposures onto the same frame, one through a strong red filter, one through a green and one through a blue. The resulting transparency (that’s what I normally shot) would show a roughly naturally colored image of anything that did not move but wonderful color effects on subjects in motion.
