There are a multitude of ways to sharpen images in Adobe Photoshop – one of the best photo editing software suites on the market. But by applying the High Pass Filter in Photoshop CC, you can selectively paint a sharpening effect onto your images. This means you can choose where to sharpen your image, likely your focal point.
The advantages of this include the ability to direct your viewer's gaze, since they'll be naturally drawn to the sharpest area of the image, while also limiting the sharpening effect to where it's needed. This is particularly helpful if you're working with a shallow depth of field or motion blur, since you're unlikely to want to sharpen these ethereal areas of the frame. Sharpening can also accentuate noise, so the ability to apply it sparingly in low-light shots is invaluable.
