John lewis christmas advert 2013 the bear and the hare.
2D- This advert is only 2D elements though out as it as the images show are only on the X and Y axis.
This is because the images are manly drawings however there are Real life items like the clock at 1.47. This would be a Matte painting and a layer as it is 2 images put on the same layer. Alpha channels  are used as well like in the fading out at 1.47 and key frames would also be used here to make the fading out work. To make key frame work you need 2 or key frames, the key frames are close together due to the fact that the transition is fast. The writing at the begining is a composite mode because 2 images are combining. Their are also layers in this as their is more than one image on top of the other at severally point in the advert.

Cadburys advert- I will boogie all night long

This advert is 3D due to it having an X Y and Z axis but its also has a 2D element to it at the end were you see the Cadburys Bar as the bar only has X and Y axis. The image is also a matte image as it is an image on top of another image ( the man dancing). The first time you see the bar it is an alpha channel because the image is coloured digitally which make it eye catchy. The advert also uses key frames but only at the end as the bar quickly fades into screen and text appears these fade in quickly by the key frames being very close together. As it fades in this is a composite mode.

This advert as both 3D and 2D elements as the start of the ride is 3d and later the ride is 2D.  Their are matte images in this when the coster sees a pillar with screens on it showing images. The alpha channel used in this was for the scene were you see the cart on  and the tracks are edited in to the ride. Their was layers and key frames used though out this advert.
