I took this yesterday morning after having grabbed my camera out of my cold car. I knew the lens was fogged when I took this but hoped I could save it in CS3. Everything I have tried has made it look too worked. I would like to have the pine trees still green and make the centre part look natural with the cub being a silhouette. Nothing has been done to it during processing or after. I do know that Noise Ninja does help.
If the original is RAW then you might be able to make this work. I would either try to tone down the BG and get more details in the darks or go for a silhouette image.
I'm not sure what effect you are trying to get. I just selected the bright zone, feathered it 44 pixels, then used curves to darken it a little. I did this about 4 times, feathering 44, 55, 66, and 88 pixels, making small darkening adjustments each time. I also darked the bottom a little with curves. Then with no selection add a small s-curve the increase contrast a little by lowering the lows some.
