By far, one of the most common issues you'll run into when editing photos is halos around a selection. This helpful video guide will show you two tools to get rid of them when using Photoshop.
Coming to you from Unmesh Dinda with PiXimperfect, this helpful video will show you two different techniques for dealing with halos in Photoshop. No matter what genre you're working in, you'll likely deal with this issue at some point, and it can be incredibly tedious and annoying to manually clean up the selection, particularly if you're working with something like hair. Nonetheless (and unfortunately), it's pretty crucial that you do clean up such haloing, as it's pretty plainly visible even to the casual viewer and can really detract from the perceived quality of an image. The first of the novel techniques in this video is using the dodge and burn tools to even out the artifacts and hide them a bit. The second is the smudge tool (surprisingly), which you can use to push the mask inward and create a soft edge (when it's appropriate to do so). Check out the video above for the full rundown of the two techniques.
