This can be done, I did the same with a painting that I wanted in detail (though I had to the additional problem of having to wait for the gallery attendant to leave the room). The main issue is shooting handheld with insufficient or badly angled light, see if they will let you use a flash. The other problem was that surfaces that look flat are probably not, so try and have the camera as perpendicular as possible, and maybe take some weights to pull out the corners of the map. In terms of aligning in Hugin, you can get this to work, but mosaic optimisation isn't as stable as normal panorama alignment; the trick is to get everything nearly right with a small number of photos and as few parameters as possible, then gradually add photos and optimisation parameters. A good tip would be to shoot a single overall shot and use this as an anchor image to align the detail photos, then delete the anchor photo once you have a rough alignment. -- Bruno -- 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.
