For the types of small misalignments that I see in this image, a nodal rotator would be the best fix. I built one myself and spent a while adjusting it to align properly with my camera. I've also developed a bunch of strategies for how to deal with these issues. The biggest one is try to get the main subject(s) entirely in frame & in focus in at least one shot. It can be maddening to have a seam going down a main focal point because it just happened to land in between two shots. Also (though it doesn't really help for your particular picture), if there are areas of low contrast (white walls, unpatterned carpet, etc.), you can force your seams to happen in those areas by using include and exclude regions. I've found using exclude regions is gentler, since an include region essentially translates to an exclude region on every other image that touches that same region. By leaving some of the low-contrast areas from both images in the seam area and making the high-contrast areas appear in only one image, enblend is forced to put the seams in the low-contrast areas where they are less noticable. --Sean -- 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.
