How to Paint with Light

Today in class, we learnt how to paint with light. I've always wanted to know how to do it and now that I do I will teach you!
To paint with light you need to take your camera and switch the mode to either TV or S. This will allow you to change the speed of your shutter.
The next thing you have to do is find a really dark room and get a few people to stand with their phones and have the light on and make a shape. If you want to be in the picture use a tripod!
The shutter delay will allow you to make the design before the picture is taken. A good time for this would be either 2 seconds or 4 seconds.
My group decided to try and make an eye. It was kind of creepy looking so we changed our design and made two eyes.

This is the first one which I find looks like Mike Wazowski from Monster Inc.

The second one we took is two eyes.

And the third one we took looks like two crazy eyes!
