A quick and lazy attempt using gaussian blur and the history brush to blur the previous image for comparison.
Contrary to popular belief, I'm really not that much of a Photoshop wizard. This entry is also a simple demonstration that shows how many bird images on many bird photo sites are not always as initially captured. I personally have no problems with this, it's just nice to be aware.
When I worked as a photojournalist, such manipulations were forbidden. Many high-end commercial customers also forbid such practices.
My image is still not perfect - I used the image as previously formatted and not a full res version. Again, if this was for sale, I would reformat the image from scratch, and probably not use as strong a blur as seen here.
You can format these suckers a million times and never get the same result - your milage may vary. :-)
Then again, you can always not worry about the background and just enjoy the beautiful Snowy.
Cheers,
Mike
