Take in what you learn on the scene and revise your shooting plan accordingly. Come back and document. Use positive body language. Move slowly and with assurance. Hug a wall, lamppost, or object to anchor yourself in a scene.
Conversation sometimes breaks the spell try communicating non-verbally with subjects.
Smile, nod, make eye contact. Finger your camera or move it to chest level. Your subject will say it s O.K. or isn t to photograph them. Pay attention to the quality of light and not just the subject. Shoot in warm light, around dawn or dusk.
