Use Adobe Photoshop's cloning and healing tools to make a figure disappear
Then type Ctrl (Command on a Mac) + J. This keyboard shortcut copies all the selected information and pastes it into its own, new, layer. Now type V to get the Move tool, and shift your copied image information to the left to cover as much of the figure as possible. Then use the Crop tool to trim out the background that you copied and moved, and to get a clear view of your progress.
