The great Jay Maisel always says that the aspects to look for in a photograph are 'light, color, and gesture.' I think he's completely spot-on. And to my detriment I think on average I spend more time looking at the first two than the third, which is arguably more evocative at times. This photo is an attempt to bring the three more into balance and start capturing some of the gestures all around me.
Somewhat related, the rather whimsically name photographer Miss Aniela has a good recent post about the nature of photography and the tension between 'contrived' vs 'natural' shots. Worth reading, I think, if only for a look at her images which are quite good, and mostly fall into the 'contrived' category.
