Well hello there photography/ 3D printing enthusiast. Today's project aims to turn something like this into something like this, using something a bit like this. I made this adapter for Nikon F mount lenses, but there's no reason it couldn't be modified for other mounts. (The files are available in step 1)
For more information on tilt-shift lenses, I'll refer you to our friend/enemy (depending on who you ask), mister Ken Rockwell.
