This was what I meant for the silky fountain water, by adjusting and playing with the shutter speed.
Photo 1: There are water bubbles and the water is frozen by using higher shutter speed
Photo 2: Reduced water bubbles with a smoother water flow by slowing the shutter speed
Photo 3: No water bubbles and the water looks silky smooth
Photo 4: Isn't this more eye pleasing than Photo 1 with all those bubbles?
