Stop Action
The idea here as previously mentioned, is to stop or freeze the action WITH FLASH and not necessarily the shutter speed and there are two ways to do it: shutter speed and flash or flash only. The decision is based on the level of ambient light. The idea here is that you can stop a subject with shutter speed and we do that all the time. But it is the times when you cannot get a fast shutter that flash helps you freeze the subject. This could be a basketball player frozen in air by flash and with no blur. A fast shutter speed is required, but the approach is pretty much the same. You can zoom in or pan with your subject. I usually use no slower than 1/125th to stop action, but prefer to use 1/250 , my fastest sync speed. The content you are trying to access is only available to members. Sorry.
