10) Extend photo backgrounds
If you need a photo that’s a little larger than the original, and it has a background that can be reproduced reasonably easily (like a beach and a sky), Photoshop Elements is able to take what’s already in the picture to produce a convincing extension of it. This is another Guided Edit, so open your photo, click Guided at the top, and then choose Special Edits.
There are several cool effects here, but the one we want is Extend background. Use the options on the right to choose your finished photo size (some social media template sizes are offered if you need them), then decide if you want to stretch the background (Extend) or clone the background to fill the space (Autofill) while keeping the subject untouched.
