And I can try . Just find a nice area, nice place to make the picture you want and then hope the weather will be nice to you . For this pictures I used a tripod and a neutral density filter. The filter basically makes everything darker, allowing you to photograph with longer exposure times, making the water look smooth. It is also used for photographing waterfalls and rivers. The aperture is set very high, so you get everything in a sharp range. And try always to photograph things with an ISO 100, photographing with an higher ISO will give more noise to your picture.
But I can recommend a tripod if you want to photograph sunsets/sunrise, because to aperture, the iso and maybe a density filter, will force you to use long shutter times.
