My original thought was to work with dried spaghetti - but that idea was snapped up pretty quickly ;-)

So I took a few days to think about it: I thought of hanging around outside the hospital to catch people coming out on crutches with a plaster cast on their leg - but this might have got me arrested!

So I finally settled for something we have ALL had experience of: shot under overhead normal light bulb with Canon EF 17-40mm f/4L lens at 40mm with a +4 close up lens attached at the front. AV setting set on f/8.
