After a newborn photo shoot I have many pictures that I need to extend the backdrop to cover up unwanted parts of the room. I have been using the retouch tool to patch in back drop to cover up these areas but this is very time consuming. Is there a better way to achieve my desired results?
If you have access to photoshop or another pixel editor, you could select a wide edge of the backdrop from top to bottom, then using a "free transform" extend the selected region wider.
That is not really a job for Lightroom at this time. The tools are available in Photoshop for that work.
