Ha! Pleased to meet you. So I don't have to convince you of stellarium's merits.

It looks like the tiles were brighter towards one corner, with some colour variation from blue to reddish thrown in. Hugin's notion of brightness variations are that they are a function of radial distance from a point, so it can deal with vignetting, but the data at hand look like as if there's maybe also a gradient on them, which hugin couldn't deal with. Mind you, if it can be conceived of as vignetting, it should be possible, and it doesn't matter if the vignetting is off-center. As far as the chromatic variations are concerned, I'm more pessimistic. > This image shows some of the Northern hemisphere with tiles we have > imported so far.

Are the images in a place where one could access them, to have a more in-depth view - and also at the metadata to see how feasible it would be to take them in en masse and run them through some batch job? If I could get my hands on some of them, I'd gladly see what I can do to help you. > So many I could have been clearer: I want to feed in pre-distorted > images and get them out with only the color and brightness blending > done. No problem. Not needing to warp them should make it easier. with regards Kay -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
