Fixing blue sky fade

What do you do in this situation; where the depth of the sky fades across the pano?

Looking at the data it looks like the right frame was 1/640 and the rest were between 1/200 and 1/320. In my excitement in being a tourist I didn't think to switch to manual and just left it on AV. Anything I can do to correct in post? I looked in Kelby's and Evening's CS5 books but didn't see an easy recipe for a photoshop beginner.

Also, if you think I went over the top on bringing out the colors let me know. I'm worried the grass is a little electric.

Lance, you can use TK's Luminosity masks to adjust this pretty easily. Just hand darken the right side through the appropriate lighter Luminosity mask and then hand lighten the darker on the left. Since it is self feathering you will get a pretty natural result. You can also use the gradient to accomplish this, but I would still use it in conjunction with the masks.

Thanks Koveh. Just downloaded TKs tutorials and actions last week and haven't really broke the surface yet. I'll check that out this week.

Read his PDF on Luminosity masks and play around with the action pack. You will find it most useful in situations like this.

Or just leave it as is. Amazing shot!

I agree with you on this Todd! The lightness on the right side adds to the visual impact. Great shot!

It looks quite normal (and good!) to me, but the blues do seem a bit 'electric'.
You might consider using a Selective Color adjustment layer (Blues) and crank the Black slider left to taste. This will lessen the intensity of the blues and eliminate the wide disparity between the darkest blues on the left and the rest of the sky.

I agree with John. Except for the electric blues, this is wonderful. Since you asked though, I've used this technique before to fix uneven skies -

Great tip, Paul....thanks!

Nice shot! Did you walk or take the train through Cinque Terra?

Thanks everyone.

Paul - thanks for the link. I will add this to my toolbox.

Dave - We did both. If I remember the geography correctly, we stayed in Vernazza, hiked to Monterrosso, trained to Riomaggiore, hiked to Manorola, decided we were beat and skipped Corniglia. That area was a highlight of the trip. That is one narrow trail though, especially when encountering Germans - they just barrel right through... 800' cliffs be damned!

Lance,

What are you using to stitch? If you're doing it in Photoshop and shot in RAW, the first thing I'd try is changing the exposure slider in ACR, then restitching. Forgive me if you already know this, but if you want to change the exposure from 1/640 to 1/320, make an adjustment of -1 on the exposure slider.

Likewise, you could normalize the 1/320 frames up to 1/200 by adding a third of a stop or +0.35 in ACR (since it only allows increments of +/- 0.05)

Are you sure you've got that in the right order, though? It looks like the right side is brighter, which would imply an exposure of 1/640 for most of the frame, then 1/320 on the right side.

The good news is that it doesn't look like any highlights are really blown, so you should be able to recover it just fine. Worth the effort, too...

Mark - thanks for the tip. I didn't even think about that. I'll play with it some more this weekend.
