The document summarizes four photographs taken by different photographers:
1. Stewart Marsden took two black and white photos of the London underground to show everyday life. One focused on people waiting and the other showed a man looking out at the skyline.
2. Simon Kennedy took architectural photos - one of stained glass windows and another of a lit bridge reflected in water.
3. Mark Pain captured iconic sporting moments - Usain Bolt celebrating and a photo of a golf ball just before hitting his lens.
4. The photos are analyzed for purpose, meaning, lighting, composition and how they depict their subject and location.
