If you shoot freehand (as I usually do) or you have a single image that you want to correct yo rely on given parameters. Or you have to have straight lines in that single image. So I think in an ideal case the result of hugins calculation will be superior to that of a lookup table that is not specific to this single camera - but the latter will be a lot better than nothing. So I would say it would be worth implementing - if you needn't do it with a different mathematical model for each vendor. I just wonder where the parameters stored in the exif data are used if they are not documented. Does some raw converter by Olympus feature automatic distortion correction? regards Joachim --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
