At this point, had to remove all remaining lights from the left extension
by painting over with a basic soft round brush set to saturation. Now it is time to give it some atmosphere and depth
With a big round brush with 14% opacity I started to paint on the fog. This also helped to decrease the contrast for the background and to achieve some aerial perspective. Next, a little color correction just to take out the greens from the scene
with a color balance adjustment layer. Next, some final tweaks for this step: I applied some noise on the sides of the set and also a 3 pixels gaussian blur to make the main focus on the back of the image – the stairs, not on the front elements. To emphasize that I made a subtle vignette effect.
by painting the margins of the set with the same basic soft round brush with 10% opacity. That’s it for this step. Next step is the fun part.
