Background

The goal of this project was to build a pinhole camera, also known as a "camera obscura" and take a picture of the image the pinhole camera captured inside of it. To do this, we had to have a shoe box and cover up any holes in tape to create a pitch black space inside of it. The only source of light would be through the pinhole and over a long time, 30 sec exposure, we would capture the light coming through the pinhole reflecting onto the white paper we layered at the opposite side of the pinhole in the shoebox. We had 3 sizes to use, .1 mm, 3 mm, and 5 mm that we switched between to capture two scenes each

Design of Box

Our box was made using a shoebox that we used black duct tape to cover the holes with. We had different pieces of duct table that had the different holes so we could easily take it off and add a different hole size on. We had the pinhole on the top of the shoebox, with another bigger hole for the camera next to the pinhole. Additionally, at the base of the shoebox we had a white piece of paper that would be where the image would be displayed.

We noticed that with .1mm, our images tended to be sharper but much darker because of the lack of light. We also noticed that our 5mm images were much brighter but also more blurry. The 3mm images seemed to occupy a good middleground
