As Sean mentioned, it isn't really about "white", it's about brightness. Whatever colors there are, the brightest parts of the image should be close to the maximum brightness your camera can record. Basically you want your camera's capabilities to e used to the fullest. So if it can record, say, 256 levels of brightness, you're using all 256 of those levels. -- 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.
