That helps, let me restate to make sure I understand. Position refers to how the camera is rotated relative to the paper. So assuming the center of the camera is always at the center of each image and the distance to the image is the same, this corrects for how the camera may have rotated around a point. View seems like it would be also covered by the position if using the same camera for all images. Am I correct? Translation is how the center of the camera has changed relative to the center of the image. Am I correct that x and y are left/right and up/down and z is the distance the camera is from the object? Barrel fixes straight lines being curved. I did find that telling Hugin to use separate lenses for each of the 2 images helps quite a bit. I stumbled upon this tutorial that suggested using 2 lenses http://hugin.sourceforge.net/tutorials/scans/en.shtml Jon -- 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.
