I was trying to replicate this effect in video form. Not the color. But the idea of the blur in a dusty/cloudy sort of feel with an obvious image (here people underneath). I know this isnt one effect and bam!, but I dont even know where to start here as I am still kinda new to AE. But i think I could handle general concepts. So any help is much appreciated in advance.!
That actually could be one effect and bam IF you have the right footage.
This was created by leaving the camera shutter open for an extended period of time while people moved around a lot.
In video, you would replicate this with the Echo effect.
