Hi Yuv, Bundles of thanks for your detailed reply. Its very informative for me. I learnt a lot from your reply.
1. simplify your hard disk's layout Harddrive is one but there are 3 partitions. C drive is system partition, D Drive I had source images and PTO, mk files, On F drive I set Hugin temp folder and it was where I have space and where I stitch images. 2. shoot regular brackets all over the pano. manual exposure, manual white balance (like you did), manual focus. all of them, including focal distance (as you did) constant Yuv, I have to shoot 291 images, 1:19 hour and 5 rows. Bracketing will increase number of images. I am not shy of number of images. I can shoot 500 or 1000 or even more. Problem arises when I try to generate CPs or stitch to full res:( But I will follow your advice. Bracketing plus enfusing images prior to CP generation. 3. merge the brackets with enfuse first Yes, Its better not to put too much load on hugin :) 4. feed the bracketed images to Hugin using the new multi-row mode; or use a script to generate an initial pto file with CPs only between adjacent images; or use Hugin's interface to select image pairs and generate CP's between each of them (tedious); or before optimizing select check the connections between pictures that may have symmetries and prune the wrong ones. How can I stitch adjacent pics? I am not into scripting. Yuv, Its 5 row panorama so in third row i shot extra image for exterior view. Its all manual and by choice. When I see that bright areas are not visible in one row, I dont do bracketing at all. In rows where I see large parts of bright areas, I do bracketing. Focus, WB, FOV are all fixed. Exposure calculation is average exposure for each row. Rotate camera 360, note exposure readings and than put a manual average exposure to camera. Please! See final panorama at Royal Garden Arches at Lahore fort.<http://pan0.net/upano.php?id=1134#pano_self> Nadir is not patched yet. This is beauty of Mughal Architecture. This small cube is made between Main entrance of fort and a mosque. There is a garden in between Fort's entrance and mosque.This small room is in center of garden and and its arches provide view to different gates of fort and mosque. Please! Watch and reply. Thanks again for help. have you ever tried to stitch extra large or gigapixel images with hugin ? Hugin can do it?
