Long exposure technique is mainly use at night to create light trails but it can also be used with day light to flatten rivers and seas or to create some magical effects on waterfalls. The technique here might require a filter on your camera to prevent the day light to burn your picture, in my case I am using a HD multi-coated variable range neutral density filter by Polaroid, and with the camera ISO set to minimum here are a few examples of what I have done. Hope you’ll enjoy.
