Boy! there sure were a lot of varieties of birds there today. The weather was kind of crappy, but all in all, it was a good day. I did a little practicing with CS5 tonight on one of my pictures from today. I experimented with the Content-Aware Fill feature. I don't think I did too bad.
First you define the area you want to fill by using a selection tool. I wanted to remove the branches in front of the Osprey.
Next, click on Edit in the tool bar
Click Fill. The Fill dialog box opens. Click to choose Content-Aware
Click Ok. Photoshop fills the area with surrounding content. Just clean it up with the Clone Stamp tool.
