Help: Blue Sky Digi Noise

[dlifesjrny]

Can someoenoe offer some help as to clear this up?
The sky fell prey to the usual jpg artiacting that is common in clear blue skies.
My biggest problem is that if I try to select the sky with the wand, the lone wispy branches at the top of the trees get selected as well, and end up getting airbrushed along with the sky I am trying to clean up.
Thanks so much in advance.


P.S. - I swear it is easier to find a tutorial on how to create a floating animated cheeseburger than something as simple and straightforward as this...

I can't see the picture, even right-clicking it.

What ISO did you use? Higher ISO, low light and low resolution causes much noise

I can't see any image, but I know what you mean.

You may need to use a better, more refined, technique than the wand tool. Maybe you could do this....

1) Create a copy of the image on a new layer
2) Boost the contrast, change levels, etc to make the branches drastically different from the sky.
3) Select the sky with the wand tool, hopefully branches wont select. Maybe lower the tolerance and make multiple selections (hold shift).
4) Click on the original image.
5) Make the changes to the sky; try Gaussian Blur, Dust and Scracthes, Despeckle, NeatImage, etc.
6. Discard the layer you used to create the selection.

Hope that helps.
