EXIF: 1600 ISO, 1/10 sec., f/4.0, 26mm focal length, no flash

This image was taken during a moment of rain in a downtown area. It depends on the amount of available light and speed of the subject, but usually anywhere from 1/4 to 1/15 of a second will grab a person in motion, and display it in a blurred way.


EXIF: 800 ISO, 1/6 sec., f/5.6, 17mm focal length, no flash

As you can see with this second picture, even a significantly slower shutter speed (1/6 sec) produced a similar blurring effect. In this image more light is focused on the subjects and the image has a slightly wider focal length. A wider viewing angle is more forgiving to moving subjects. This is why in most cases you must use a tripod for most long telephoto shots, even in daylight. Having more light focused on the subjects also does a better job of freezing them while in motion.
