At some point I bought a second Pentax Spotmatic from a thrift store without a lens. Not sure what to do with the extra body, I decided to purchase a pinhole lens cap on eBay and try my hand at some pinhole photos. Using Pinhole Assist on my iPhone, I was able to capture an accompanying image with the settings used for each film shot. Within the app you start by metering with the phones camera, set the film reciprocity, make any necessary calculations for aperture, and then save your profile for future use. These images were made on Worldwide Pinhole Photography Day, April 24, 2016.
