Bikes are a great topic for photographers, perhaps because the vehicle is connected to romantic rides along river banks, under the shadow of maple trees, or on old cobbled roads in the drizzle.
I used to scoff at people who pointed their butts at the sky and took shots of bikes from various angles, from tires to derailleur. And yet one day I found myself doing the exact same thing when an old woman walked past me with a big grin on her face. Here is the product (not a good shot with a dreamy background as described, though), with an application of high key exposure. Anyway, this shows a fact that a photographer always adopts a very bad posture, so excuse me... ;-)
