Albert Lea Senior High School issued the following announcement on May 13.
ALHS 10-12th Graders in Photography class worked on Pinhole Cameras during the 4th Quarter. Students worked in groups to turn cardboard into a functional camera that they could put light-sensitive paper inside to capture images around the school.
The main goal was to create a functional camera and challenge students to come up with a creative idea for the outside of their pinhole camera. The top images are the photos developed from their cameras, and the bottom ones are the inverted images for each.
