We finished with the ambient effects and now in the finishing touches. First you need create a merged copy of entire image (Cmd/Ctrl + Opt/Alt + Shift + E) and convert it to Smart Object (Layer > Smart Objects > Convert to Smart Object). Go to Filter > Sharpen > Smart Sharpen... Set the values as shown in the image below. This sharpness up the entire image including you can manually adjust the sharpness of shadows and light.
The second stage of sharpening will work with the details. Go to Filter > Sharpen > Unsharp Mask... Set Amount: 111%, Radius: 0.8px, Threshold: 1 levels.
Now add the main spot of color. It is necessary to focus the viewer on the main character. Add adjustment layer "Gradient Fill" with following gradient #030303 > #0d2f4b > #144a68 > #4b90a5 > #92cfd2 > #d8eee3 > #ffffff, Mode: Radial, Scale: 150%, Reverse. Set Blending Mode to "Soft Light", Opacity around 70%, Fill around 60%.
And in the final add some contrast. I used an adjustment layer "Curves". I edited the curve for each channel to show contrast in certain areas of the image. Use image below to set up curves. Set Blending Mode to "Luminosity" and you're done!
That's the end! I hope you enjoyed this tutorial and you'll find there are a lot of useful information. This is the final result. Now you can add the desired text and create a poster or cover.
