Fixing a noticeable sky blend after photomerge?

Hello,

I created a panorama using photomerge with CS, and while the result turned out okay, there is one particular section of sky, with a noticeable blend, which I have been unable to fix.

I cropped the offending section, and you can see it here: http://danniken.home.comcast.net/PanoFix01.jpg (60kb, 820x868, .jpg)

My question is how can I go about fixing this? What I "think" I need to do is some type of compound gradient, from right to left, and from top to bottom. Is there any way to do something like that?

How would you go about fixing this?

Thanks for any suggestions you are able to offer,

Jon

A couple of pointers ...

I've had best results if I shoot the series in manual mode - so I don't get tone variations caused by different shutter speeds. A leveled tripod helps too.

Consider a 3rd party stitching program - The Panorama Factory and AutoStitch are both very good (the letter one is free, and does multi-row stitching).

As far as fixing your issue goes, a last-ditch way is to measure the colour values of the top and bottom of your existing sky - then replace it with a graduated fill layer (guaranteed cloudless day :)

I would try to "apply" some of the clean parts of the sky to the defective ones:

mark clean area -> "new layer from copy" -> resize and move new layer (ctrl-t) -> blend new layer edges with background (e.g. layer mask).

The result could be something like this:

drawback: the scaling and/or mirroring of the image parts will change the noise ("grain") distribution in the image, a keen eye can easily notice the manipulation.
