Panning is a technique where you choose a slow shutter speed ie. 1/250 to 1/60sec and follow the bird as it flies past. The two panning shots below were taken at Sardis Park at 1/125 sec. If you are a little slow or fast, the bird may be blurry, so it takes some practice. Ideally, the bird should be as sharp as possible, and the background a blur. If you are using internal stabilization, it may be best to turn it off, and you want to keep the slow shutter speed.
As you can see from the two photos above, I like to use colourful, contrasty backgrounds when I pan to bring attention to the subject. Give it a go and share your results with us. Ken Pugh (Chilliwack)
I would use ISO 200 - 250. You want to stop motion in the bird, but have lots of motion in the background. An ideal shutter speed would range from 1/30 to 1/250 sec. Every situation is different - closeness of the subject, speed of the bird(s) etc.
