Camera Obscura

I made a my camera obscura out of a new balance shoe box. Unfortunately, I lost my digital camera this semester so I had to use my friends one which has a max exposure time of 8 seconds. Hence the resulting photos were not nearly as good as I wanted them to be.
Here's my shoebox camera:

2 mm

1 mm


The smaller the pinhole size, the more focused the resulting picture.
