Used a CPL filter for a pano, any way to fix the uneven sky?

Right well I wasn't thinking and forgot to take off my CPL filter when taking a set of photos to make a panorama of Geneva. Very annoyed with myself for not realising at the time! As a wide area of sky is covered, the colour has come out very uneven across the image as you can see below:

Geneva%20Panorama%202%20800.jpg


I've tried playing with the colours in Lightroom but I don't have much experience with PP at all and haven't had much success!

Does this look like it would be easy to sort out with Lightroom only? I don't own Photoshop.

I have the full size TIFF image produced by the panorama program if anyone is willing to give it a try themselves.

Cheers!
 
Which panorama program did you use? Does it have anything built in that evens the exposures that might be appropriate?
 
Nice vista! You can def see the cpl cut through the haze.

Not much experience with pano's but have used a cpl on a wide angle lens and got this effect.

Could be wrong but think its notoriously difficult to correct in lightroon alone. Could try if you have individual raws you may have some latitude for correction.

It might be easier to composite another sky into the image in Photoshop. Seen this done before. forget which pro but he had this library on his pc of just skies! Tho I'm sure there's some other options...

Oh post the tiff.. there maybe some eager toggs who'd like a challenge.

The local ajustment brush might do it (you'd need a few at least) but it's crude compared to what photoshop could do, this is slightly tricky as it's so uneven, think I'd be tempted to do as sharris says and simply replace the sky.
 
Hi guys, thanks for your replies.

The program I used is called Hugin. It looks like it has some basic exposure settings but I'm not sure it would be able to correct something like this.

I am very new to lightroom, I haven't bought it yet and am just using the 4.2 release preview at the moment. I will have a read about the dodge and burn tools and attempt at using those to correct it.

Unfortunately the images were shot in RAW...another mistake by myself (can you tell I'm new to this?!). So this fact may limit me somewhat as to what I can achieve. Replacing the sky sounds like a good idea which I may look into if other routes fail.

For anyone interested, here is the original TIFF image produced by Hugin. Image is pre-crop hence the random lady standing at the side!

Would Photoshop Elements 9/10/11 deal with evening out the exposures in the panoramic photomerge option?

Perhaps download the PSE 11 trial and have a go?
 
You might have some limited success using a graduated filter on the right and one on the left. Then on each mask drop the exposure. But you really need to take it into (something-like) Photoshop. Have a look at this video on using a graduated filter in Lightroom http://www.youtube.com/watch?v=LJyj8sm2nvQ


And dont apologise for using RAW - that is the right thing to do.

That's definitely not a mistake! Lightroom works on the RAW files, and you can easily go back to the originals if you get so far with the processing and then decide you don't like your results.

Unfortunately I can't advise on how to rescue the pic. Polarisers do this on single images as well, especially with a wide angle lens. It's most easily diguise-able if there are scattered clouds in the sky and arguably the clouds actually make a better image anyway.

Thanks I didn't think of that. Might even see if I can give the Photoshop trial a go and see what I can come up with. Finding the time to fiddle around is quite difficult at the moment though with uni!

Sorry I got that the wrong way round, my mind must have been some place else! The photos were taken in JPG format.

I realise RAW gives you more control and my camera is now set to capture in RAW all the time now. Couldn't believe what was possible in Lightroom recovering shadows and highlights from a RAW file!
 
I think your best bet is to get the PS CS6 or PSE 11 trial, then use the dodge/burn tools. i had a go just with your small JPEG preview and it seemed to work pretty well :)
 
try cut out part of sky you want, save on new layer, transform to size of layer, add layer mask, reduce opacity so you can see horizon then paint out the bottom, then up opacity to your choice
