There are a few things you need to know if you want to remove an object from a photo in Photoshop Express. First, make sure that the object you want to remove is not part of the photo itself. If it is, you will need to use another program to remove it. Second, make sure that the object you want to remove is not in the foreground or background of the photo. Third, use a clean brush and start at one end of the object and work your way around it. Finally, be careful not to damage or remove too much of the object.
