Brighton, East Sussex.
On the beach at Brighton we see a seaside photographer looking through his camera. Two women come walking along, dressed in overcoats and eating ice-cream from wrappers. The man persuades the women to have their picture taken with a toy donkey and they agree.
Small boy Dave and his shaggy dog Dusty are watching all this and decide to set up in competition. He puts Dusty in position and cleans his box camera. The photographer approaches a couple who are walking along, but they refuse. Dave waits until they get near him and persuades them to pose with Dusty. They eventually agree.
Dave adjusts their pose so it is just right, but then spends so long in trying to figure out the angle and technical details that the couple get fed up and walk off. Dave doesn't realise and takes the photo (with fingers over the lens). When he looks up from the camera he sees Dusty sitting there alone.
