Как вернуть в исходное значение блок при параллакс эффекте?

$(document).ready(function(){ 
    $('#scene').parallax({ 
        mouseport: document.getElementById('container') 
    }); 
});

body { 
  background: #111; 
  margin: 0; 
} 
#container{ 
    width: 100px; 
    height: 100px; 
} 
img { 
  display: block; 
  width: 100px; 
} 
 
.scene { 
  max-width: 500px; 
  margin: 0 auto; 
  padding: 0; 
} 
 
.layer:nth-child(1) { 
  opacity: 0.15; 
} 
 
.layer:nth-child(2) { 
  opacity: 0.30; 
} 
 
.layer:nth-child(3) { 
  opacity: 0.45; 
} 
 
.layer:nth-child(4) { 
  opacity: 0.60; 
} 
 
.layer:nth-child(5) { 
  opacity: 0.75; 
} 
 
.layer:nth-child(6) { 
  opacity: 0.90; 
}
