• Wait until it’s almost dark outside. Take your camera and go and sit in a busy tourist area. Choose a building or statue to photograph. Place your camera on a tripod and set the shutter speed to 30 seconds or more (if you don’t have a tripod, something stable, like a chair, will also work. If you don’t live close to a busy street, just get one or two people (or even your dog) to move up and down past the camera during the 30 seconds).
  Take a look at your photograph. Do you see a lot of people in it or just the building/statue?

-In the picture below I myself was walking in front of my camera, wherer the light is. I walked back and forward many times during those 30 sek. As you see Im invisible in the picture.

• Wait until it’s dark. Go and stand on a bridge over a busy street (or look from the window of a high-rise building). Place your camera on a tripod and set your shutter speed to 30 seconds or more. Inspect your photograph. What do you see?
  (If there’s no bridge or high-rise building close to where you stay, find a street where there are some cars driving or alternatively ask a few people to help you by driving up and down your street. You can even pay an taxi/uber-driver. Ideally you should capture this from a bit higher than street level. You can ask a hotel in your area to use their window or the flat of a friend that stays on the second floor. Some buildings have a secret stairway to the roof… be creative, and safe!)

• Ask a friend to help you with this activity. Choose a dark room in your house and switch off the lights. Place your camera on a tripod and set your shutter speed to 30 seconds or more. Ask your friend to “draw” a picture in the air using a flashlight. Take a look at your photograph. What do you see? This fun activity is called light painting. Try an easy pattern first, but also a more complicated one.
