Grey Haze

[lurch]

This photo of Denali (Mt. McKinley) was taken at an angle through a (probably) tinted train window. I've been able to get luminance and color balance where I want it using curves in Lab, but my feeble attempts to get rid of the gray haze on the right have all been less than successful. Do the RTP magicians have any suggestions on how to approach this?

A curve adjustment layer to increase the contrast.
Masked this layer on the mountains - more on the front range, less on the back.

Lurch, is this headed in the right direction?

I tried with channels again.

I used level adjustment layer with a layer mask for the right hand side. The mask had a gradient that had been blurred with a radius of about 200. I used a combination of Hue/Saturation and Color Balance on the masked right side to increase the blue content. I also used Bart Hickman's tutorial ( http://retouchpro.com/tutorials/?m=show&id=264) to reduce the overall haze.

I used unsharp mask on the mountains and blurred the sky.

Tried... but still visible. (snif)

Thank you each and every one! What a marvelous and helpful response.

Ro - Wow! Your contrast adjustment made a huge improvement in that photo.

Murray - That indeed was headed in the right direction. What was it you did?

Chillin - Whatever you did with the channels helped. More details?

Duwayne - You got it far better than I ever could. Thank you.

Manta - I know the feeling!

Now that you all have pointed me in a good direction, I'm game for another try. Will post results.

Gratefully,
Carole

Probably not the most efficient workflow - mostly just winging it

1. Duplicate layer, set mode to overlay, filter -> other ->highpass 37px
2. merge visible into new layer - quick levels adjustment & increase saturation by 25
3. Duplicate layer from 2 and set to overlay again, highpass again at 2px
4. Merge visible again
5. duplicate and add 2 passes of full strength noise reduction (filter->noise->reduce noise -> strength 10 sharpen 0)
6. Mask noise reduced layer in as required
7. merge visible and duplicate again
8. finish off with contrast +10 and mask in where desired

NancyJ - Winging it or not, that came out quite nice. Another set of things to try!

Using bits and pieces from just about every one of you, this is what I finally came up with. Again, many thanks to all.

I used the same method fixing another picture... see my post here
I might add that I used a lot of feathering in a selection.

Just contrast the color component and little bit USM in dark areas.
