If you want to sharpen a photo in Photoshop, there are a few things you need to do first. First, open the photo you want to sharpen in Photoshop. Next, select the Sharpening tool from the toolbar. (You can also find this tool in the Tools panel.) To sharpen a photo, click and drag your mouse over the area of the photo that you want to sharpen. The sharper the edge of your selection, the more sharpening will be applied to that area. To soften the edge of your selection, drag your mouse away from the area you want to sharpen. To finish sharpening a photo, click on the OK button in the toolbar or on the Sharpen Image dialog box that appears. ..
