Whether it be a drink can or an orange, many everyday items can be turned into a pinhole camera, including potatoes. Justin Atkin of The Thought Emporium proved it by figuring out how to turn starch and salty water into a photographic recording medium.
After some trial and error, it was found that cyanotype, which involve laying an object on paper coated with a solution of iron salts before exposing it to UV light and washing with water, works really well, but just takes too long. If time isn’t an issue, this method creates stunning white and Prussian blue images. Next, he tried silver-nitrate, which was found to produce satisfactory images, but creates a negative image that has to be manually inverted.

For the potato images, the next step is probably making paper out of potato fibers, then constructing an entire camera and film out of said fibers. Just because it SOUNDS easy probably doesn’t mean it is, so I wouldn’t mind if there wasn’t a follow-up about it,” said one commenter.
