The group is seperated into pairs. One of the pair will be blindfolded, the other will be that persons guide. Each group is given a digital camera. The guide then takes their partner on a walk around a chosen area (not known to the blindfolded player) while on the walk the guide will give the blindfolded player the camera, and get them to take pictures of various objects and buildings. The walk should last for at least 30 minutes but can last for longer, say 1 hour. The blindfolded player should take about 30 pictures or so, more if they are blindfolded for longer. Once they have been guided back to the start their blindfold is removed and they can look at the pictures they have taken. They then become the guide and the guide becomes the blindfolded player. A different route should be chosen for the second walk.
