Sultanahmet Camii, Istanbul, Turkey

The Sultanahmet Camii, or “The Blue Mosque,” completed in 1617, is visible in the middle of the image. There is a wind shadow on the lower side of the land that causes the water to appear darker than other areas in the scene. What’s most interesting here is the difference in reflectivity between the moving water in the channel and the still water in the harbor area. Changes in reflectivity can be measured and used for not only water, but things like differentiating crops. Other features on the water are caused by boat wakes and wave-current interaction, and the moving boats appear blurred because the ships were moving when the image was taken.
