Free Triptych

My lab charges for the whole roll of film whether you shoot one image or 38 (the Contax uses every inch), so I experiment with the unused frames after a shoot.  I have overexposed images 4 or more stops, I've shot images of my dinner, and I've played with slow shutter speeds.  Here is a series of the last.  

Tech Notes:

Fuji 400H shot with Mamiya 645 AF and 80mm f2.8 lens.  I don't remember the shutter speed, but I'm pretty sure these are cooked.  Processed and scanned by Richard Photo Lab.
