Split into groups of 4-5 (make sure there’s one leader in each group), and give each group a camera (or they can use their phones if they want).

Draw up a list of things/objects/ situations they need to try to capture on film. Be creative with the list – make sure you include some simple tasks, but also some trickier things to find (or do).
Allocate points to each item depending on the difficulty.

For example:

Points Photo of…
10      A red four-wheel drive
20     Members of your group squashed into a public phone box (if you can find one!)
20     A member of your group on a swing
30     A member of your group shaking hands with an old man
5        A McDonalds sign
30     A member of your group behind the counter at McDonald’s
10      A cat
30     A member of your group holding a cat
5        A stop sign
10     A personalized number plate
5       Members of your group at a bus stop
5     Members of your group on a pedestrian crossing
30   A member of your group in a swimming pool
10    Your whole group “planking” in a park

Be sure to set a time limit when people need to meet back. Tally up the points and whoever has the most is the winner! If you have time, share the photos on a big screen.

Other variations include using video cameras (rather than still photos), or tagging photos on Instagram using a predetermined hashtag, and/or tweeting on Twitter for “live” updates during the night. Make sure to add all the photos to Facebook, Instagram or your group’s web site!
