I found this shot in my library dated back in 2014 during the fog season in Dubai. When the fog hits the city & reach a very high point, it’s better & highly recommended to shoot above the fog. In my case I was on the 75th floor. By time the fog gets lower until it reaches ground zero & vanishes. As you can see in this shot that the fog is covering most of the Marina bay area including the high towers. My advise is always to shoot on a long exposure mode by adding a ND filter 3 stop or less depend on the timing & available light to have smooth wave layers.
