The challenge in April was to create an image that rocked! A rock or rocks needed to be a significant part of the image or picture story. They didn't have to dominate the image, but without them, the image would have been significantly diminished. Rocks could have been in their natural situation or an artificial environment, but they should not have been dressed into building material - that would have been stone after all. Participants could have taken a pictorial approach, or gone hard and technical.
