I don't think that this is a bug or a wishlist item. I don't think there
is a good way for hugin to know when the photometric optimization went
wrong, apart from asking the user somethink along the lines of "Do the
colors in the preview look flat/washed out/wrong?".

Closing as invalid?

Title:
  colors in some areas look like resolution has been lost

Status in Hugin - Panorama Tools GUI:
  Triaged

Bug description:
  If I stitch certain 'blended' panoramas  I get an artifact that looks like color resolution has been lost.

If I stitch as 'Fused and blended' (even though I only have one set of images) I get much better, but still compromised results.

I tied the PTgui demo on the same set and the colors came out fine.

Here is a link to the problem as produced by 'blended' and 'fused and blended':

I have seen this to differing degrees with all the revisions of Hugin I have used.  Current version 2010.1.0.5161  Windows XP.

I have been told this happens when there are large areas of bright sky in an image.  That is true of this set, though I have seen it when there is a light in the images as well.  I have tried various schemes of optimizing, not optimizing, underexposing, turning down the brightness with identical results.

Any ideas?
