The first photograph is hard to see. Though, really, that shouldn't have come as a surprise. The Harry Ransom Center makes it exceedingly clear on their website that not only will the image be difficult to make out, but that each viewer will in some sense be reperforming its discovery. Their instructions for viewing the photo include a short epigraph by Helmut Gernsheim, a photohistorian that rediscovered the piece in 1952. Of his first viewing of the photograph he writes "No image was to be seen. Then I increased the angle—and suddenly the entire courtyard scene unfolded itself in front of my eyes. The ladies were speechless. Was I practicing black magic on them?"
