is special about making photograms?
Directness certainly. And in my case a form of magic and unpredictability.
The techniques you can use are many.
To my mind comes an experience I had when I was 15 (47 now).
One bright summer's afternoon I lay beside my girlfriend.
I held my arm around her.
At the end of the day it had made a white mark on her reddening back.
We had both been too afraid to move.
