This image is a long exposure using the natural darkness of the evening and also an ND filter to lengthen the exposure time to allow the movement of the clouds to become what you see here. Of course there is more to it than just slapping on a dark glass in front of the lens and firing the camera's shutter.
Check out our landscape photography workshops for more information about learning how to improve your photography, particularly using filters for long exposure coastal landscapes. These small group photography courses are suitable for all levels and individual attention will be given to help you improve whether that is in understanding exposure or finding your style with composition.
