I have spent about 5 hours trying to do the best I can with what I've got and it's not too bad. I need to colour correct the whole scene now which is no mean feat given that the sequence comes from about 10 different sources!
I haven't looked at the 97 release yet to see if that offers up some more of the original shot. My initial thought is that the 97 Jabba may cover less of the background than the 04 Jabba does. In actual fact I don't have the 97 release of ANH anywhere.
As for what Declan says - watch this space...
