Gear Needed:Camera that allows shutter speed control and a tripod.Recommended Gear:Remote shutter release(to avoid wiggling the camera) and a Circular Polarizer or Neutral Density Filter.  If you don't have the filters you will need to shoot when light levels are low, almost to the point of getting dark - after sunset and before sunrise.In this video I use a Canon T5i with 18-135 STM lens with a Circular Polarizer on a Benro MeFoto Travel Tripod.I mention Back Button Focusing in this video, helpful to keep the camera from refocusing each time you try a shot.Even with the filters the best time is near dawn or sunset, the rest of the day is too bright, even if it is overcast.
