I'm trying to resize just a small part of a photo, leaving most of the photo unchanged. But no matter what I have tried, I end up keeping my selection unchanged and resizing the rest of the photo. The process I'm following is:

1. Mask the area I'm trying to resize.
2. Select the content-aware photo resize tool.
3. Click Prepare.
4. Resize the photo.

I've also tried the same process with inverting the mask. Either way produces the same results - the small area gets protected and the rest of the photo gets resized.

I read something in the help that said we can't protect more than half the photo or you'll get an error during the Prepare stage, but I don't get an error. Also, I have definitely done this task before - I have the photos to prove it!

What am I doing wrong?

How can I resize just a small portion of a photo?

Thanks in advance!
