Went to Richmond Nature Park at 7:15PM. Should have gone there earlier. Light intensity was slowly dropping under the trees as I was waiting for the rufous hummingbird to return for a quick sip at the sugar water every 15~20 mins. Keeping aperture at 6.3 with speed as fast as possible. This is a shot taken on a tripod-mounted Canon 300mm f/2.8 IS II lens, the 2.0X III TC, with Canon EOS 5D Mark II. ISO 1000. Evaluative metering at +2 stops: 1/800 sec.
