CS194-26: Image Manipulation and Computational Photography Project 2

Building a Pinhole Camera

By Jason Zhang (cs192-26-adg) and Alex Kassil (cs194-26-aam)

Part 1: Building the Camera

For the first part, we gathered materials. From left to right, top to bottom, we have black duct tape, black cardstock, a pocket knife, a digital camera, white paper, a pin, film, and a shoebox.

Unfortunately, we didn't end up using the film.

We turned the shoebox inside out to get black floor/walls for free!

We put tape and black cardstock over the bottom/walls/lid

Here we can see our aperture slider

Here we create a hole for the camera lens to fit into the box

Here is the finished shoebox pinhole camera complete with pinhole and screen!

This was much harder than expected with a pinhole camera. Here are our best attempts at drawing the letter "A".
