Silky-smooth skies

Brief

Use a long exposure to take a photograph of some silky-smooth skies. All the clouds should be blurred together, but make sure that some of the picture is in focus, or it will look like you just took a blurry picture of the sky. For example, setup your camera on a tripod to feature a nice building, but make sure that you include a lot of the sky. Then, use a long exposure to blur the moving clouds and the blue sky together for the perfect shot.
