I demonstrate the clone tool and how to make a fake shadow using layer transparency. Also mentioned is the filter noise and dust and scratches to distort a background.
PIxlr E has an auto AI background erase feature that is handy. In the video we use the clone tool to erase the background. Photopea has a more AI tool as well. This is so different when I learned photoshop back at ECU in the 90's. LOL
