Add a Color Balance adjustment layer and change the Midtones and Highlights settings:
Make a Color Lookup adjustment layer and select Soft_Warming.look. On this layer mask, paint on the bottom and the middle of the canvas to remove the effect there.
Create a Curves adjustment layer to increase the light of the sun’s area. On this layer mask, paint on the rest to keep their lightness and contrast.
Make a Levels adjustment layer and alter the Reds, Greens and Blues values. Lower the opacity of this layer to 70%.
Add a Curves adjustment layer to darken the whole scene. Paint on the model’s face to reveal the lightness there.
Make a Brightness/Contrast adjustment layer to increase the light around the sun. Paint on the rest so it won’t be affected by this adjustment layer.
Use another Curves adjustment layer to darken the edges of the canvas. Paint around the sun’s area to keep its lightness and make a nice contrast for the whole scene.
Create a Selective Color adjustment layer and change the Reds and Yellows settings:
Make a Photo Filter adjustment layer and pick the color #00ecd9 to change the color of the sky a bit. Use a soft black to paint on the rest to keep the warm color of these places.
Add a Vibrance adjustment layer to enhance the final effect. Paint around the sun and the right edges to reduce the saturation there.
