Hi Leon,
I'll look up Karl Chapman - thanks for the tip!
I'm actually not sure what type of emulsion we used in class last week, but I'll be buying some to try some more at home. An interesting was, after the paper was exposed and developed / fixed / washed, but before it was dry, you could move the black parts of the print around with your fingers by rubbing it - could be a useful / interesting technique for manipulation
