Getting the whole picture sepia except one person requires masking. Masking can be performed on the basis of color, luminance etc. The best way to perform this, depends completely on the scene where you want to do this. It might involve a lot of work when the scene is not suitable for it. So you better show a picture of the scene that you would like to use.

Thanks Theo ! Excellent link.
Regarding the second post - Think of it as a wedding reception. When the couple is dancing, i want to keep both of them in native color and rest all should slowly turn into BW or sepia.
