I'm probably not the first to think of this, but I came up with the idea just today. The idea is to use the Vignetting filter on a layer mask for example to create a depth blur. Here is an image of an Eagle in a tree I shot today and applied this effect. It would make a good Desktop background.

Looks like a young, healthy eagle. Do they eat people's chickens?

These Eagles eat mostly fish from the river they live on. I have seen Eagles attack and eat baby goslings though. They are scavengers and will eat dead animals now and then. Never seen them eat chickens, but it is certainly possible.

That certainly will make a beautiful Desktop wallpaper! Very nice.
