I thought shooting the human body and overlapping a realistic version on top was very interesting. Mikeal Graff photographer - toronto did exactly this a few years back, very talented photographer.
As well another idea, would'nt it be neat to do cat scans or MIR of the body fluid path or nerve path or blood paths and overlay them onto the real body, I thought of this for Colour work , printed on Cibachrome .
How much to rent a private MIR lab with technician.???
