Photographed it after Sunset on banks of Nethravathi River. Placed my camera on a tripod, framed the scene, set the auto focus to wide and aperture to the smallest f/8 . Clicked with self timer of 2 sec to negate any camera shake, when pressing the shutter button. A image or sky reflected on water makes an interesting monochromatic image with tonal variations. Such reflections also add symmetry to an image.
