| this is only a guess after peeking at the exif data, but considering this is done at F10, 1/160th of a second, ISO 100, with a 50mm lens, I would have to think it is either done using trap focus, or an infra red trigger for the camera. Maybe a remote push button but I don't think so.
Probably the camera is tripod mounted next to a feeder, but pointing away from the feeder so you only see the bird trying to land. |
