faux tilt shift

So today halfway through thermo, we were talking about the idea of un-attaching the lens, moving it a bit, and snapping a photo. I promptly went home and tried it. The APS-C lenses I have didnt work out too well but the 50mm from the 80's worked alright. I couldn't focus on infinity at all but for anything in between, I was able to shift the focal plane a bit. Here are some quick and dirty experimental shots:

I'm gonna keep my eyes peeled for a super cheap medium format lens on craigslist. Then things might get a little more interesting.
