M. C. Escher's prints and sketches don't need any help when it comes to warping minds. One photographer found out how to take it to the next level, though, and the way it went down is as impressive as the result.
Refracted here in a drop of water is Escher's Relativity, taken by Reddit user Smsilton. Not just any drop of water, either — one falling freely.
Smsilton described the process thusly:
Yeah I used the Canon 60mm macro f/2.8. I shot at ISO 640 and 1/250. It took about 150ish shots to get that one, ~2 hours. The hardest part was focusing, in the set up picture I posted in the first comment you can see a piece of string above the eye dropper. I would let that hang down off the eye dropper and focus on that, then move it and squeeze the dropper and the shutter at almost the same time. I have like 30ish more pictures with the drop clearly in the shot but the sketch behind it isn't in focus, this was the clearest one I got.
Smsilton can now join the club of photographers that successfully captured what could have been lost in the blink of an eye, such as this crazily improbable shot of the ISS passing before the moon. See Smsilton's shot in larger detail by clicking on this pic right here:
