This great tutorial video will show you how to better sharpen your portrait images in Photoshop.
Getting it right in camera is only half the battle. Oftentimes what separates a good from a great image is the post-processing. Aaron Nace of Phlearn demonstrates a great technique for sharpening portraits in Photoshop with clear step-by-step instruction. Along the way, he offers a multitude of helpful tips and insights including how to ensure your sharpening effects only the details and not the color of your image and how to make use of smart objects and filters for maximum versatility and capability.
The crux of the process is using a High Pass filter with an appropriate Blend Mode, bringing out detail in the highlights and shadows of the image. As with all things Photoshop, subtlety is key. Keeping the High Pass filter radius small and adjusting the opacity of the layer to taste will result in a much more professional result. Additionally, you need to be strategic with the areas you choose to sharpen; for example, most of the time it will make sense to focus on sharpening your subject's eyes, eyebrows, and lips but not the rest of their face.
