Photoshopuniverse teaches you how to enhance the colors of photos using Adobe Photoshop. You get a photo and duplicate that layer. Set the blending mode to Soft Light. You repeat that step, only the blend mode should be Lighten. The shadows are now darker. You can change the blend mode opacities to 60%-70%, but both layers should have about the same opacity. Also make sure that the white values are not to white and that details, like faces, are still OK to see.
