I'm always amazed to see any glittering moment on a body of water surface. This time I share glittering light that seen on the Petuguran Lake (Bumiayu, Central Java, Indonesia).
The sun light created a magical stripe of glittering light on the water surface. Glitter patterns composed of countless bright points of light that changeable, blending together to form a smooth path of glittering light when watched from a distance. If you see closely at a glitter pattern, you can notice individual points of light. Each point of light is a specular reflection of the sun, called a sun glint. Glints occur on the water where the local slope provides a direct specular reflection of the sun.
A light source, such as the sun, is then reflected from multiple spots on the surface. As the wind-rippled surface moves, so do individual glints. But the ensemble of glints produces a glitter pattern whose shape and size can be related to the roughness of the water and the viewing geometry.
