I was camping at a park in California last week and took some panorama shots of the lake. As I have found common when shooting panoramas the vignetting in each individual image can cause problems when stitching them images together so I try to remove as much of it as possible. Still, even after those adjustments, the stitched image still showed considerable light variations in the sky. Here is the stitched image.

I looked for some function in APB that would allow me to even out the luminosity of the sky, but did not really find anything. I tried several blur filters, but they did not help. In the end I had to replace the sky. I was wondering if there was something in APB that would allow me to even out the varying brightness levels in the sky. Does anyone know of anything that could be done?

 

Here is the result with the new sky, but I would prefer not to have to replace the sky if there was some way to smooth out the luminosity.

Mike, did you try Hugin? It's open source and it is absolutely fantastic. Just make sure you select the options as in the screenshot.

 

Photometric: > Low dynamic range, variable white balance <

 

It works without any flaws, better than Autopano Giga, and it works with scanned images without Exif data.

I used this software some years ago, but not recently.

 

I have been doing my panos with Panorama Studio 2 and it is pretty good, but sometimes fails when there is just too much vignetting for it to match the sky tones properly.

 

I will download the try this again. Thanks for the link.
