Steps:
1. Stand on the bridge when dusk,
2. Zoom out and stay around 45-degree viewing angle for a few seconds, the sun color will change to reddish.
3. Move the camera to Bird's eye view, the sun color will change to normal.
4. Back to step 2 then zoom in, the sun color also become normal.
5. From step 2 while the color is reddish, rotate camera to south, look at the sky. Gradually the reddish sky will become cloudy and dark.
