for weddings, i agree with voodoocat, and say to use kodak porta NC. it's mostly meant for skin tones, which is what you would want.
however, the first time i used it, i hated it, cause i was trying to do these brightly colored shots. then i asked my professor what the deal was, and she let me know that it's really good for skin tones. if you research it enough, alot of places will tell you it's perfect, for weddings especially.
