The shutter is a small curtain in the camera that quickly rolls over the image sensor and allows light to shine onto the imaging sensor for a fraction of a second. If u slow down the shutter speed u'll be create "Motion Blur" this effect use in the sphere advertising in order to show the speed of an object. And high shutter speed use for fix up object .The nature photographer most of the time for creating beautiful image of motion and dynamics of river or waterfall will use this Technic.
Last night i took this photo with Motion Blur Technic.
how is it?
