Eureka!
Through the miracle that is DIGITAL PHOTOGRAPHY, I've discovered a type of glass that turns black and white images back into colour again! I'm gonna be rich!
It was a swine to create but I had fun with this...
I asked Ayesha to pretend to be holding something and then created the 'sheet of glass' in CS3. Getting the edge effects right was the hard part but it all worked out in the end.
