Pin-Hole Camera Reflection

On Friday, which was when the event took place, i wasn't there. Since i didn't know what happened, i asked some other people. Other students said that they used their  pin-hole camera and went to a dark room with red lamps since the photos they were going to take would get ruined by regular light. They then cut photo paper and put it into the back of the camera. After, they would seal up the cameras and then turn on the main lights. They went outside and held the camera for 15 seconds on the object they chose for the picture. Then they went back inside, turned of the main lights, took out the paper and put it where the other ones were stored, which was a bag.
