To get the exposure right on the rest of the photo the sky was somewhat over exposed -- which isn't uncommon at all for this type of shot. I'd start by seeing what you can do PP and see how much it improves by adjusting the exposure on that portion of the picture. Next time you could use a split ND filter to try to get the dynamic range closer. You could also try a polarizing filter -- depending on the specific situation it can have a dramatic impact. You could also take a few shots and combine them with HDR software.

Edit -- looking again at the image it probably would improve quite a bit with PP. You might want to post a full size copy in the retouching forum and ask folks there what they would do to improve it.

As DWEverett said, if you were to take the photo again, underexpose by 2/3 stop. With photos like this I find it easier to get the sky right in the exposure and then fix the land on the computer, rather than the other way around.

Since you already have this photo, turn the luminance down in the blue, and then maybe shift the blue hue over to the purple side a bit.

With image open in Photoshop...

  • Select sky area using Magic Wand tool. Shift-click into any unselected areas until all areas down to sky-line are fully selected.... (marching ants around whole sky.)

  • Feather sky selection to suit your image megapixels, say, at a rate of 3 pixels per 8MP of image.

  • Now create an Adjustment Layer.. (suggest Levels, just for convenience,).. a dialogue opens to set Blending Mode for the Adjustment Layer..

  • In the dialogue's Blending Mode drop-down, select Multiply Mode. Sky immediately darkens, but leaving the clouds pretty much unnaffected. Alternatively, set Multiply Blending mode in Layer Pallet.

  • Tune final result with Opacity slider of Layer...

  • Or, for stronger result, right-click on layer in Layer pallet, and select Duplicate Layer from the drop down. Second layer created....sky gets yet darker. Now tune THIS layer for opacity.

(Your sky seems to be rather dusty.)

Thank you.

The Multiply trick is always worth trying for beefing up a weak sky, because it is quick to apply.... so even if it doesn't work particularly well there isn't a lot of time/effort wasted.

Adjustment layers and blending modes are very powerful tools within Photoshop.... and they work without increasing file size much at all. This helps to make them quick. No new pixels, you see.... just an algorithm applied to ones that are already there... kinda like getting the image to process itself.

Also, if there any real lack of data for the algorithm to get a grip on, and the sky texture goes gritty, it isn't much of an effort to blur the sky to some degree, while the selection is still live.

You can easily fix that on photoshop with some burning or painting. A good example of fixing a sky is shown in this video:
