On visiting Shanghai, especially in winter time, there is a good chance you will get smog. On this particular day, the smog was quite bad although the sky did change to an orange like colour at sunset. I decided to go for a different look by manually changing the in-camera white balance to 4000 Kelvin and also changing the tint a little bit more to the red (pink) side.
This is my entry on the #longexposurephotography weekly photo challenge.
