In this picture, you can see the animated pig coming out of the box. The lighting is dimmed but the Christmas lights make it feel more bright than it actually is. This then creates a warm atmosphere which reminds the audience of Christmas which is the purpose of the advert.We then move onto a scene where the lighting is brighter so therefore the audience recognises the supermarket. You can see the aisles of the supermarket with all the food freshly stocked.
In this picture, you can see the advertisement for the m&s food. You can see how the food is well lit so that it is easy to see. In the scene, you can see that the food is placed slowly that the audience have time to really study the food.
