With people spending over the odds on eBay on busted lenses to get bokeh it does make me wonder whether the next trend will drive prices for Vaseline up to get that nice soft focus effect.

I'll even chuck in an expired Polaroid Black and White film pack so you can get that 'didn't quite get the film separated quickly enough so now its got black blobs all over it' look.
