Sorry, my mistake for not explaining what happened: I did use aligned TIFF files. The problem is that SmugMug won't allow me up upload TIFF files, so I converted them to JPEG files (where the masked region looks black) before uploading them. > I think there are two general enfuse workflows for a bracketed panorama shot: > - first enfuse every single bracketed stack of jpgs to preferably a 16 bit > file (tif), and stitch those Which is essentially what I'm doing via hugin. > or (should work if you used a tripod) > - stitch all different exposure steps with the same settings so you get three > panoramas (-2, 0, +2 EV) and enfuse those Which I didn't. > Both workflows don't exactly propose to first remap the images. > > This little experiment... > - make sure canvas size is identical (I pasted one image on top and aligned > using difference mode, then cropped to these smaller boundaries) > - mask the black undefined areas using an alpha mask, save as tiff > ...gives me a better result than your "No options" example: >> With different options to enfuse, I have the following results (I'm >> using -l 1 in all cases to see where enfuse makes its decisions): >> * No options: >> >> http://rlk.smugmug.com/Photography/enfuse-test/14365255_gYhFw#1064010124_sBN5B > This image containes a pseudo halo which looks as if the black "frame" is > actually used by enfuse. I don't believe that that's the case, since I actually did this on TIFF files using an alpha mask (that had been created by hugin, or really nona). -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
