This shot has been post processed in photoshop. If you look back to how I altered the Goldfinch and Greenfinch in flight, it is the same principle as this. I copied and pasted the bird into a new layer before adding a blur to the background. I then cloned out where the feeders had been and added the blur again. I pasted the Sparrow back onto the background layer and cropped to how I liked it. Finally a bit of sharpening and here we are!!
I hope that you like it and all comments and critiscms are welcome.
