Other examples of good times to use very slow shutter speeds to create blur are; moving vehicles, trains, cars and congested city traffic; blurred panning effects where the subject, a runner, bicyclist or car is clear but the background around it is blurred from the camera following its movement Compatible with the Canon EOS M Compact Camera.
