Img4 (Windows 8)

img4, originally known as Seascape Initiation, is a wallpaper included in Windows 8 as part of the Earth theme. It was taken by Microsoft employee Bala Sivakumar in 2009, who also took the photograph for Windows 8 Release Preview's default wallpaper. It depicts a rocky beach at La Jolla, San Diego, California, USA.

History
Bala Sivakumar was visiting San Diego during late 2009. He was with his friend, Arun, who showed him one of the places where he often takes seascape shots. On December 26, 2009 Sivakumar captured the shot, his first one of a seascape, using a Nikon D700 at ISO 200, 80.7 secs, f/22, with 25mm zoom. Years later, Sivakumar submitted the photo for use as one of Windows 8's wallpapers in an internal contest. Here it has been cropped to remove most of the sky, and has noticeable added saturation.
