    Back in the early days of x-ray technology some shoe stores would x-ray customers’ feet to make sure the shoes fit right

      Is she…staring directly at the X-ray itself?

      Like, I don’t pretend to understand how X-rays work. I know they emit a wavelength of light that goes through soft tissue like nothing.

      And I know normally, nowadays (or at least before digital came around), there would be a piece of x-ray sensitive film on one side of the object, and a bulb that shone x-ray onto it, which would then be developed (i think in a process sort of similar to polaroid but I could be mistaken again).

      The dentists panoramic X-ray that swung around your head like something out of a sci-fi VR movie was the coolest, imo.

      But…it looks like she’s looking directly at his foot through a special lens? Does it just put some sort of filter between her and the X-ray that makes it look like a really bright flashlight through the fleshy bits between your fingers?
