Pattern wasn't difficult to understand or to photograph. Rhythm on the other hand took a bit more thought. I think I've grasped the concept but trying to explain it to my husband proved a little difficult.
DSC_0175 : Pattern - A shot of brickwork on the pavement in the town centre. They form a distinct pattern made up of diagonals which links back nicely with the previous exercises. I was careful not to get any benches or feet etc in the shot.
DSC_0176 : Rhythm - The straight vertical lines of the back of the truck lead your eye nicely to the snake slithering across it. You then follow the snake to it's head and end up at the forked tongue. Your eye goes from top to bottom and then left to right.
