What is that movie where this lady takes a picture of herself in a white dress?

hey, i dont really remember what the movie was about, but at the end or near the end, this woman goes to the woods or a field of gr or something and puts her camera on timer and on a tripod, and stands in front of it and the camera flashes. she's wearing a long white dress and kind of looks like a ghost.i dont know. i dont think it was a horror/ghost movie though. please help!!! i dont think this scene really has much to do with the movie :/ does anyone know?!? thx!
