Similar to what I posted yesterday, this one is a duotone. Duotone will be familiar to users of photoshop or anyone involved in printing, it is a process used in printing on presses where there is only two colors. For my purpose it allows tinting of a black and white or greyscale image to give effect and is easily manipulated because you can control so accurately the amount of color added to light, medium and dark tones.
