Hi Harry, thanks for the prompt response.
I export from Apple Aperture3 to 16-bit TIFF with the color profile sRGB IEC61966-2.1. It was my believe that sRGB was the default color space on OSX, so loosing the profile would not lead to disaster. Obviously I was wrong, but I have not yet discovered how images without a profile are supposed to be handled in SL. The finished pano's get imported back into Aperture for final adjustments and are then exported again as 8-bit TIFF and sRGB to Pano2VR. There also seems to be a color profile issue with that application which I will try to tackle next (or maybe it is just a scaling thing). My whole flow is color managed and calibrated using icc-profiles all the way. As a stopgap I can use Preview to assign the correct profile and after that the input and output of Hugin are indistinguishable. I will try to figure out where the profile information is living in the images. In preview it shows up under General Info as "ColorSync profile: sRGB IEC61966-2.1" and under More info -> General as "Profile Name sRGB..". Is there any reason why exiftool -all:all can't find it, all groups and all writeable tags, right?
