A large slab of ice had formed on the canvas covering my patio furniture. When I stood it up I noticed the amazing pattern. Ran in to get my camera and after a few shots, ran back in to get a blue scarf to place behind the ice and give it some colour. It was one of those times when I had no idea what to expect, looked at my screen after the first shot and was chuffed with the result of my little experiment. It made it worth almost having my fingers frozen to the tripod.
