15-463 Assignment 5 - Pinhole Camera
By Jitu Das
Overview
I built my pinhole camera from a box as shown below and used a Canon EOS XTi DSLR
camera to record the image projected by the pinhole camera. I used an external
trigger to minimize vibrations on the camera for many of my images. I also used
the bulb exposure setting to take very long exposure shots.
