Mom, Chris is making fun of me.

OK, I just got back a test roll from my hacked TLR zone plate camera.

This is the only one worth reporting on. Its taken in traffic at night, but
I flipped the image because it works better like that. Unfortunately, this
doesn't really showcase the zoneplate qualities, unless its to give the
lights a softer glow. But it certainly has a lot more life than the other
shots on the roll.

Focal length, 90mm, ASA 100, exposure 4 blocks at 25mph.

I'm about to build a rig to use as a mount for the cameras that will fit in
my moonroof opening and allow me to also reach up and trigger the shutter
open and closed.
