No the artefacts are because you are not rotating the lens around the 'no parallax point'. This is nothing to do with the lens distortion. >Is that possible with fulla?

Assuming that you do want equirectangular panoramas, then you don't want to convert to rectilinear at all - Slices from (corrected) fisheye images will do the job. So you can use fulla/lensfun rather than nona. >What am I missing? Does it mean, that the parameters are not working >with fulla and that I have to calibrate using hugin? The parameters are not working, ptgui works slightly differently and these images would need to be rotated 90 degrees for the same values to apply. However the image still looks really wrong, I strongly recommend you recalibrate the lens with hugin. -- Bruno --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
