Found a box with a couple of polaroids, this is from the County Show so they've been in my bag for a few weeks and got rather grubby. The marks are crystallisation of the chemicals. Having scanned this and the other print toady it's apparent how off either my scanner or laptop screen are/is. A little bit annoying - I've had to do a bit of adjustment in PS to get it similar to the original
