How to create a cool background texture in 3 easy steps
1. Find a river
A river or a lake on a windy day—water with small waves.
2. Find a building
A building reflecting in the river/lake, that is. More lines in the architecture, more intricate the texture. A sunny day helps.
3. Shoot the water
Shoot that building's reflection in water. Play with the picture, change the colors, get crazy if you feel the urge.
