I have read several times now that a technique for taking better street photographs is to listen to music whilst shooting. Firstly it relaxs you, making you less self concious, visible and helps blend you in with the crowd. Secondly people are less likely to approach you and complain if they see you wired up with earphones.
I often find myself seeing a subject on the street which I want to photograph but feel it would just be too imposing to blatantly lift my camera and shoot. It feels a bit rude to stick a camera in a strangers face.
Anyway being one to give anything a go I will try it out and report back.
