Glenn - I agree, but in Izzie's case, I don't think this would be as effective as in the image here. You are shooting is a situation where the subject is a bit brighter than the background, where in the case of Izzie's images, we are effectively in a back-lit situation where significant parts of the background, i.e. the sky are brighter than the subject. Applying a slight Gaussian blur is not going to correct for that.
Even brightening the statue and then selectively darkening the background is only going to take us so far.
I suspect a re-think on how these images were taken will be required too. Shooting closer to sunset and using artificial light and a large light modifier would work, but might not be practical.
