After that, I added the fog layer with "Linear dodge" and 53% transparency (Fig.31).
At this point I'd reached the DOF process, so I made Gaussian blur to the DOF pass with a very small value (Fig.32).
To achieve the DOF blur, I used the colour select tool and selected the white parts in DOF pass, copied the selected part from the main image and used Lens Blur with a definite value. I repeated this part for each different area in the DOF pass; the darker the area, the less blur it has (Fig.33).
After that I wanted to add some glow to the sky, so I selected the white parts in the image, copied them to a new layer and give them some Gaussian blur (Fig.34 & Fig.35).
Then I added more dirt to the closer parts of street, to give them more darkness and variation in the texture (Fig.36) .
Then chromatic aberration was added and some parts were retouched (Fig.37).
Finally, I increased the sky glow and added birds and a walking man in the distance. Then I was done (Fig.38)!
