Houston Hardin is a doctor who collects firearms. The idea for his X Ray Guns series occurred when he had a gun shipped to his radiology office. A pair of curious workers, knowing his hobby decided to "take a peek" without opening the package. They CAT scanned the package, sent him the result, and that's when the lightbulb went off. Hardin perfected the imaging process to create beautiful prints that capture a little known side of gun design.
