Hi Cristian, The simplest way how to do HDR panorama in hugin is to load bracketed shots into hugin, then you can continue as usual, but your approach should also work. At the preview window bottom are some some controls. If you are blending HDR panorama, I suggest changing output to HDR which shows your pano as gamma 2.2 by default I think (it can be changed in preferences). If you're making fused images (something like tonemapped panorama) the you have to load bracketed shots, not the HDR ones, because exposure blending is based on a bit different algorithm which AFAIK doesn't work well with HDR input. The problems you're experiencing seems like not correct setting of exposure. You can easily change this in small combo box at the bottom of the preview window (note that changes will be visible only when output is set to LDR in the same window). Then for stitching final panorama check in Stitcher tab "Blended panorama (enfuse)". --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
