Overview

We build a pinhole camera using a pringles cardboard box and a digital camera.

Design Details

Pinhole Size

We based out pinhole sizes around the formula given, 1.9 * sqrt(f * lambda), which worked to 1.9*sqrt(0.00055*210) = 0.64mm. So we based our pinhole sizes around that. We tried 0.5 (a little lower), 1mm (a little higher) and then 2 mm. We noticed 0.5mm was too small of a hole and not much light got in. 2mm lets a lot of light in, but blurs because we get too many light rays. So it seems like 1mm was the goldilocks size, just right!

Box Design

We build the box to allow for different pinhiole sizes by leaving a dedicated pinhole portion in the box. As you can see from the first photo there's a dedicated portion in which different black rectangles(with different sized pinholes) can be dropped in.

Photo Details

All photos were taken with a 15 second exposure time.

Final Thoughts

This project did a great job making us balance and tweak our settings. This project was also a ton of fun! These projects are great because we get to see tangible results!
