Sorry for replying so late. In principle you don't need the overall scene brightness to be constant for calculating vignetting, so long as the light distribution remains the same. hugin can 'optimise' exposure simultaneously with vignetting. In practice, I'm not sure what environment would behave like this - Maybe a room with a small diffuse skylight. -- Bruno --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
