I've been using Photoshop for many years. I've written articles and recorded over 30 minutes of video on the subject of sharpening using the wealth of excellent sharpening techniques Adobe provide, so I figured I'm qualified to bring up one of the most negatively discussed and ubiquitously bemoaned tools in the existence of image editing, that's right - not just Photoshop but the whole image editing world - the Sharpen Tool. Here I plan to explain what its purpose is, what it really does do, and when and why it might come in useful.
What is the Sharpen Tool?
