Realistically Fill in Gaps in My Image?

Start by making a selection of the area you need to fill in (like the gaps that appeared when I created this pano. I just clicked in them with the Quick Selection tool [W] to easily select them), then go under the Edit menu and choose Fill. When the Fill dialog appears, if it’s not already selected, choose Content-Aware from the Contents pop-up menu. When you click OK, Photoshop looks at the surrounding area, and then rather than just filling with white or black, it makes an intelligent fill based on how that surrounding area looks. It does a pretty brilliant job of it most of the time (as seen in the inset above). When it doesn’t, though, it misses by a country mile and it looks terrible. So, if (when) that happens to you, you’ll just have to undo it (Command-Z [PC: Ctrl-Z]) and then find another way to fill it in manually, usually using the Clone Stamp tool (see page 166).
