I just simply start with the first image, drag the secong image ontop, change the opascity of the second layer to make sure they are in line with each other as close as possible. then just use the lasso tool or if you want an amazing fine clean edge, use the magic wand but that does take a very long time. then just put a small fetaher of around 2, select inverse and then delete. do this for all of the pics.
The first one took me around 2 hours finish, still have to touch up a few of the edges ( some of them are a bit messey)
Cheers all for your comments
Ill post a few more up today.
