In this 37th tutorial, we are going to learn about Sharpen Tool. This is one of the most basic tools in Adobe Photoshop for sharpening pixels to have a better look and feel. Like Blur and other Brush Tools, Sharpen tool has options to adjust brush size, angle, blending modes and strength percentage. Sharpen tool enhances the edges. We can also protect detail before sharpening. This tool is also used in retouching projects. The use of sharpen tool is very much like other tools in which we use brush-like options. We can sharpen the whole image, the selected part of the image or in case of masks, we can hide or reveal sharpening effect accordingly.
