Ok, let’s start. This is a very simple effect actually. We start by duplicating the layer (Ctrl + J).
Then, create two blank layers.
Fill each layer with these colors: Brown (#5c2e18) and DarkBlue (#1f4c76) using Paint Bucket Tool (G)
Then, choose Lighten for blending mode for both layers.
Adjust the opacity for the layer accordingly; in this case, I set the opacity to 40% for both layers. Now, select the duplicated Layer from beginning and sharpen the image by using High Pass ( Filter > Other > High Pass ) Set the Radius to 2.
Choose “Overlay” for the blending mode and adjust the opacity.
Voila! You are done! Here is the final result.
