taking badminton pictures is always an interesting topic, so let's dive into that more. here is a picture from the ongoing China Open. what can we tell about the picture? what can't we tell about the picture? we know it is a motion shot, the shutter setting didn't manage to freeze the racket motion. we know that it is exposed correctly, and the color balance seems to indicate that no post-processing is done to enhance the brightness. in other words, the exposure is set correctly at shutter time. depth of view is pretty shallow. the front player is blurred. so the aperture is probably maxed out with a moderately telephoto lens, may be a 200mm @ f/2.8? my guess is that it is taken at 1/250 or so. the presense of noise means that the ISO setting is also quite high, i am not surprised if it is ISO1600 or 3200 we don't know if it is cropped from a large image or not. there is a certain clarity to the image. but there is also some noise. are the noise an artifact of the ISO setting? or from cropping/enlarging? any expert care to comment?
