If you want to darken an area in Photoshop, there are a few different ways to do it. One way is to use the Levels tool. To do this, first select the area that you want to darken and then click on the Levels button (it’s located in the toolbar at the top of the screen). Next, click on the black slider bar and drag it towards the right until you reach the desired darkness. You can also use this method if you want to lighten an area as well. ..
