I have this image
that I want to even out the sky. Its a 6 shot vertical pano from lake tahoe. as you can see the sky is much lighter on the left and righ hand side of the image than it is in the center.
any ideas on how to fix it? I want to offer this image up as a print at DPC prints

| I believe the best way and the quickest is if you have Photoshop CS. Click on Image > adjustments > shadow > highlights |

Something like this?
Selected sky by using magic wand to rough select as much as possible, "select similar" to grab the rest of it, and the rectangular marquee to subtract foregound pieces from selection.
Made 2 duplicate layers from background. Turned off BG layer and top layer, loaded sky selection on middle layer, filled selection with a light blue and used hue/sat to adjust it to a natural color.
Made top layer visible and active, selected a darker blue as foreground color in the tools dialogue box, applied a foreground-to-transparent gradient in the selection, adjusted hue/saturation and faded the opacity of the layer until the gradation looked natural.
Did a little burning on the rocks.
Flattened image.

I think robert's is a bit un-natural looking. I would suggest trying a radial gradient rather than a horizontal one - just make the radius really big and to one side, so its only slightly curved in the final photo and slightly lighter towards one side at the bottom.
Do you know what I mean? I can't access PS to do an example right now.

well I have been playing with the photo and just cant get it to look right. I will keep trying but all my results are not very natural looking or the area where the sky meets the mountains gets really jaggy

The suggestion to use a radial gradient is going in the right direction. You need to create a mask that will allow you to gradually adjust curves on the sky, and not on the land. That means a very soft gradient across the sky in a roughly radial (but not quite) shape. When you mask off the land, also use a very soft edge, don't try a sharp selection, that almost always looks false, and is just a LOT more work. There are some cases where a hard-edged selction is mecessary, but those are very rare.
I'd build the mask using both gradient and paintbrush (at very large diameter and abour 10-15% opacity).
Here's my 3-minute try at it:
On this, I ran two passes of gradient curves adjustment, fading each to luminosity blend mode. After that I smoothed things a little with a blur on just the sky. As a final step I added 0.7% of uniform noise (luminosity-based). I also tweaked curves generally on the image. This is surely far from perfect, but reflects the small file and the minimal time spent.

Yeah, it's unnatural looking 'cuz I did it on a lo-res copy and I did it fast. The principle obtains, though. Radial gradients are very tricky to work with, but can be effective. I've also had considerable success with doing it as described above, then merging the faded gradient level with the BG, cloning off a new duplicate, and using the burn tool at a very large diameter and 5-7% intensity to sweep an arc through the corners, overcooking it slightly, then fading that layer down to a natural appearance.
