I think there is a definite bug in the Assistant here. If the initial
geometric alignment isn't very good then the photometric alignment
always goes wrong and you get these colour artefacts.

The Assistant should skip photometric alignment and rely entirely on
EXIF EV values if the geometric alignment isn't 'good'.

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

Status in Hugin - Panorama Tools GUI:
  Invalid

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?
