When taking a long exposure of flowing water a tripod is a necessity. An exposure of a few seconds gives the water a velvety effect. Longer exposures up to 30 seconds gives the water a milky effect, like the image below. I’ve read that images of waterfalls never seem to do very well in photo contests. Oh well, I still like to experiment with slow shutter speeds to create a graceful blur.
It was a nice evening to take images, there wasn’t a breath of wind, a warm temperature and a beautiful sunset. In the first image I like how the boardwalk slowly curves to the right and visually draws you in, leading your eye to the gate and the stop sign. In the second photo the sun was low on the horizon and as it shone through the lantern it created an interesting green shadow on the wall behind it.
