About This Photo:
This photo was taken in Singapore at Bird Park bird sanctuary. The exposure used was ISO1250, f/5.6 and 1/500sec @ 300mm. The camera and lens used was my Canon EOS 70D and Tamrom 70-300mm f/4-5.6 Di SP USD Lens. The shutter speed of 1/50sec was used for two reasons, one of which was to prevent camera shake due to effective focal length of 480mm (300mm X 1.6 crop) and mostly to make sure the subject was frozen into frame and keep as sharp as possible. Since the faster aperture possible on this lens at the 300mm end is f/5.6, this forced the camera to use an ISO speed of 1250 to get a proper exposure.
