Understanding the Method
The provided reference highlights the use of Content-Aware Fill for expanding a background.

This is particularly effective for backgrounds with patterns, textures, or relatively consistent details.
Step-by-Step Guide Using Content-Aware Fill
Here's a breakdown of the process based on the reference and common Photoshop workflow for expanding backgrounds:

Create Space: First, you need to make your canvas larger to create the empty area where the background will expand.

Image > Canvas Size. - Increase the width or height (or both) depending on which side you want to expand. Use the Anchor grid to decide where the original image should sit within the new, larger canvas.
- Click
OK. You will now have empty space (usually transparent or white, depending on your background settings) around your original image.
- Go to

Select the Empty Area: You need to select the new, empty canvas space you just created.
- You can use the Marquee Tool (
M) or Lasso Tool (L) to draw a selection box around the empty area. - Ensure your selection covers only the transparent or empty space you want to fill with expanded background content. The reference mentions "make sure that background is selected", which in this context refers to selecting the area to be filled with the background pattern.
