Hmm. I'm disappointed I haven't got anything better to include, but haven't had enough time this month. I love bokeh - but haven't got much to show for it.
Anyway, I dug out my Nikon FM2 a couple of weeks ago which I hadn't used for a while and noticed it had some Fuji Neopan 1600 B&W film in it - so thought I'd try and capture some grainy bokeh and see what it looked like. The experiments didn't work out that well, but here's my entry, an abstract. It's basically of a piece of shattered glass (window of a bus shelter) with sunlight shining through, with the points of light out of focus to make grainy little heptagons showing the shape of the lens diaphragm. The lens is a Nikkor 20mm f/4 (7 bladed diaphragm). This would have looked better in colour for sure. My job is to make up the numbers this month!
