I was down with Nicky yesterday evening in Chavez Park in the Berkeley marina. The wind was blowing and the sun was setting. Nicky was playing with a little girl we met. Both kids were throwing pebbles into the Bay.
I had the camera on a tripod, with a polarizer, and stopped it way down. Post-processing included copying some clouds from another image from the same set onto a layer, blending with about a 70% opacity in Multiply mode, applying an nik Color Efex Bicolor filter (with user-defined colors and settings), a fair amount of cloning and patching, and the usual level and sharpening stuff.
