Need some help with processing wedding picures.

[keleinad]

Hi guys
2 years ago I have hired photographer to shot my wedding.
Some on the pictures were made with blue wall in background.
Than this guy was "pasting" those pictures in different places.
It wasn't perfect but now I have some nice pictures.

He also gave me those original pictures.
I want to try the same thing with them. I was already wotking with PS so I wasn't expecting any bigher problems , but I was wrong.

I have no idea how to cut or mark veil so there will be no blue background.
Here is park of the picture ...

I think you're gonna have to do a lasso. using color range will take out some of it, but the gradient is gonna be slightly problematic.
