how to remove double shadows on panoramics
Discussion
well the competition is encouraging me to process some of the panoramics i have stored on my cpu but i have come across a stumbling block and i would like some help.
after doing a 5% test of a 360 pano in autostitch (to check it would work), i got autostitch started on soing a full size version. 2 hours later and it had just finished!!!!! in the main it has worked, but there is some strange overlap around my girlfriend in the foreground and i dont know how to get rid of it. i presume it is because she may have been in 2 slightly different poses in the 2 pictures that have her in (i have learnt to give autostitch lots of overlap to play with).
i guess it may be possible to cut her out of one of the original photos and stitch it again (assuming there is overlap), but i would prefer not to give my cpu another 2 hour crippling job if it can be avoided.
can anyone help?
this is a close up of sarah showing the strange effect. as it has "ghosted" her, i am having lots of problems bring her top half back to looking normal.
this is where the full size image is. i dont think flickr likes the fact that it is 15 times longer than it is wide though so you cna only see it when you go to the full size page.

if you know how to sort out htis problem could you please just give me some hints and i will try and sort it myself (unless you are very bored and want to try for yourself)
cheers

Out of interest what ISO was that shot at? It looks very noisy... And your sensor needs a clean! 
yeah i know my sensor needs a clean, its quite terrible in those photos.
im fairly sure it was ISO 200. i dont know why it would seem noisy. is it possible that autostitch is the cluprit?
I've found a similar effect in some of my panoramas where the overlap area has had a person in it in one of the photos but not in the other, could that have happened with yours? ie included one in the set which has that part but without her in it? it shows up more with a lighter colour behind the object/person like sky or water. The other effect, the area around the edges of her I also got in some panoramas where the same object was in different original shots but at a slightly different angle as I'd moved a bit when I turned to take the shots. It was also much worse when the same object was in 3 shots rather than 2, so I ran autostitch again with only the photos I needed in it,avoiding excess overlap between multiple photos, and it came out much cleaner and sharper.

well i have had a go at chopping out the bad part from one of hte original photos and pasting it over the panoramic and it has worked to an extent. i still have some blending to do but i think it is much better than it was with the transparency.
a strange phenomenon though:
autostitch seems to have increased the size of the panoramic! i had to increase the number of pixels in the bit i was pasting onto the panoramic to get it to lay right. this might explain why the picture looks a bit grainy as that process is likely to add more noise. very odd though, i just dont know why it would do it.
