I'm afraid I'm going to mess with Mark Page over on the Manchester Photography Blog a little bit. He seems to have started running a little series called New Clichés of Photography. He's only up to number 2. I just took a look at it, and less than 30 seconds later looked at another blog and knew right away, there and then, I was looking at just that - a new photographic cliché. So, rather than stealing Mark's number three, I'll just classify this as #2a.
You can see Mark's first two here: No.1 (the Dodgy Painting) and No.2 (Mounds & Heeps)
