Slow It Down! Shooting At 1/20th Of A Second (With 15 Examples): "We’re not in a yoga class, but a nice slow breath and steady shutter release finger will allow you to take your shutter speed to a new low. And by low, I mean slow; 1/20th of a second, for instance. While it is not the slowest shutter speed out there, 1/20th of a second can lead to some interesting effects; from causing intentional blur in waterfalls to allowing for available light shooting situations and increasing depth of field. Then throw in a tripod or solid surface and more options appear."
