Better results with Content Aware Fill in Adobe Photoshop CS5

A brief explanation: Content Aware Fill isn't magic, and it isn't some freakishly new technology that's been sent back from the future.

It's basically a more sophisticated version of cloning, in that it takes visual elements from within your document, and attempts to blend it in with the area you choose to delete when you click the "fill" button.

The secret here is to simply eliminate the data that you don't want used to generate your fill, or in other words to choose the CONTENT that Photoshop is AWARE of when it's calculating how to process your image.

Good luck, and have fun.
