Would this be worth it? How often do you reach a few dozens bad pixels in an image? Let's say 100 pixels (this seems a lot, I'd buy a new camera long before) on a 10 MPx image, which means 1 pixel out of 100000. And those wouldn't be completely wrong, if the camera did a correct job of "fixing" them. -- Frederic Da Vitoria (davitof) Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
