Metal and plastic are great, but these DIY cameras are stand-alone pieces of art
An Airplane Hangar
The World's Largest Photograph measures a massive 111-feet wide by 32-feet tall. In order to create such an enormous image, six photographers and 400 artists turned an F-18 airplane hangar in southern California into the largest camera ever made. There's an entire book dedicated to documenting the process of making the image which required insane amounts of materials and person-hours to do the work. It was displayed at the culver Center of the Arts, but doesn't make many appearances these days because of the sheer size.
I'm sure that there are a ton more out there that we've never seen, so feel free to share any other creative DIY cameras here in the comments. And don't worry if they're not made of a skull or anything weird like that. We can appreicate beautiful cameras just as much as we do the creepy ones.
