I don't know why yours seem to be coming in under the radar Dave, but I would swear I've only just seen this. I like it a lot and I've been thinking about giving this method a try myself. I did use it once at a festival in Bolivia, but I couldn't get the hang of wonky slides. I straightened one or two, but I haven't tried since. How do you find it? I'm used to working with hyperfocal distance because the last few years of street photography with my appalling eyesight left me with no choice. I thought Chris was using a wide aperture though...
