Camera Obscura and Bedroom

One of the precursors to our modern cameras, is the camera obscura.  Camera obscura is similar to a pinhole camera, without the film.  Camera obscura was used to project a subject onto a screen, in order to trace the subject’s outline.  You can turn a room into a camera obscura, by blacking out all the windows in a room and cutting a small hole to let light through one of the windows.  The result is an upside down projection with left and right swapped as well.  As you can see in the image above, the scene from our backyard is projected into our bedroom.  Melissa and I used cardboard to cover the windows and I cut a quarter sized hole for the aperture.  The exposure for this photo was 7 minutes long at f/5.6.  This is a pretty crude test.  I’m going to be doing more research and working at refining the process.
