There is no photograph more inherently photographic than another.
I'm not particularly invested in, nor do I really care about, photography in a general sense. It's a medium that's relatively ubiquitous, readily accessible, and that I have some facility with, so it makes sense for me to use it.
[X-ray's] accidental discovery in the late 1800s fits seamlessly into modernity's fascination with, and belief in, the power of technological transparency: the desire to domesticate time (cinema), to preserve and capture the surface of the fleeting (photography), to see inside (x-ray).
