It's the lighting. In the church, there's tons of light streaming through the entrance, to enhance the fact that both Aeris and Zack are dead (kind of a "wishing you well from heaven" thing) and just spirits. The second picture is better 'cause she isn't lighted by a large light out from behind her; she's stuck in a sunny field. ^_^
