How do you write scripts attached to a game object that move the main camera

I have a game object that I am successfully tweening with javascript and iTween. I want to have this script create a reference to the scene’s Main Camera, and tween that camera. How do I do this? Here’s my code so far (which doesn’t work).

var igniter : GameObject;
var camera : GameObject;

function Start () {
	lighterUp();
}

function lighterUp(){
	iTween.MoveTo(gameObject,{"y":-2.75,"time":3,"easeType": "easeInOutQuad","oncomplete":"lighterTurn"});
	
}

function lighterTurn(){
	iTween.RotateTo(gameObject,{"y":0,"oncomplete":"lighterTurnIgniter"});
}

function lighterTurnIgniter(){
	iTween.RotateTo(igniter,{"x":180});
	iTween.MoveTo(camera,{"z":-50}); //Doesn't Work
}

camera is a property of component, probably defined like this :

public Camera camera{ get{ return GetComponent< Camera >(); } }

Unless that script is actually attached to the main camera, it will return null. Try Camera.main.
