Step 1: Items needed
-A camera, one that has a shutter speed adjustment. Otherwise you are just photographing water all day and will not get the silky water effect. :0(
-If its windy, something to weigh down the tripod, such as one of those nifty sand bags you hook onto the underside of your tripod and load up with sand and rocks.
-A super steady hand or a remote control shutter trigger.
-A warm friendly personality
Step 2: Locate some moving water.
Approach the body of water slowly, so as not to spook it.
