We all know that digital images are made up of red, green and blue “pixels”. Often, to capture this, sensors are in some kind of side-by-side pixel array, like with Bayer and X-Trans or layered, like Foveon. But that’s not the only way to create a full colour image. Many video cameras do it with the use of a prism splitter and three separate sensors capturing red, green and blue signals which are then merged together.

Mike and JohnBen at Clovehitch Productions wanted to try to replicate this last method using black and white film. They wanted to see if it was possible to capture just the red, green and blue parts of the spectrum on three separate shots, and then merge them back together to produce a full colour image.
