Photoshop is a powerful image editor that allows you to create layers. A layer is a group of images that are combined together to create a single image. You can add text, graphics, and other elements to your layers using the tools in Photoshop. When you add an element to a layer, Photoshop creates a copy of that element in the layer’s document memory. If you want to move or delete an element from a layer, you must first remove the original element from the document memory and then add the new element to the document memory.
