This week, students in Laurie Hartman’s Photography 2 class created images using a technique called pinhole photography in which a tiny hole replaces the lens.
The students used either a light-proof paint can or a box camera that they made with a small hole on one side. Light passes through the aperture and projects an inverted image on the opposite side of the box, known as the camera obscura effect.
“The process involved a lot of experimentation. You can’t adjust your aperture or your shutter speed, and there are a lot of variables to consider,” said Ms. Hartman. “We experimented with different sunlight conditions and different locations. The students discovered that when someone walks through the shot, you get a kind of ghost effect. They also found that an exposure time between 20 and 40 seconds worked best.”
Ms. Hartman hopes to experiment with indoor pinhole photography next semester with her advanced photography students.
