If you take photos of people or things often, you may find that there are scan marks on them. These marks are caused by the camera scanning the image too quickly, and it leaves small lines or squares in the photo. To remove these marks, you can use Photoshop’s “Scan Tool.” This tool allows you to move the image around so that it’s easier to see where the scan marks are. You can also use this tool to make them smaller or disappear altogether. If you’re using a digital camera, be sure to take care when taking photos of people or things as there may be some scan marks on them that you can’t remove.
