The final

Part one: the challenges

Each challenge gives you a situation and no instructions. The clock runs, the camera counts every refusal as a mistake, and a hint costs you a star. Three stars means no mistakes, no hints, and under par.

• Reload and shoot
• Change lenses mid-shoot
• Double exposure
• The stuck lens
• White, with texture
