Some people build homemade cameras. I can see the appeal in this, although I wouldn’t know where to begin trying to do it myself. One of the most intriguing aspects of building your own camera would be the ability to build it as big as you’d like—even if that’s, say, 14×36 inches. Darren Samuelson is building a camera that big—which is so large that it uses x-ray film in lieu of traditional orthochromatic black and white photographic film. Check out this cool video of Darren in action with his big ol’ camera at DIYPhotography.net. I guess in a world where film choices are fairly limited, x-ray film actually broadens the spectrum of options available to you.
