This render was done in two styles to experiment with different moods. While they are both the same base render, different effects were used to accomplish the final effect.
The first render stays much truer to the original render by simply adding focal depth blur and using a depth map to create atmosphere.
The second render goes a more surreal, fantasy route and adds significantly more atmosphere and overlays another background to add more sunlight to emphasize the brachiosaurus' height, which extends beyond the trees. In addition, the RAW filter was utilized in Photoshop to color correct and add lens distortion for the desired effect.
