Ginormous files

As I was beginning to set up backgrounds for the "London calling" sequence, the files quickly exceeded the 2 gigabyte limit of Photoshop documents and I had to begin saving them as PSB files (Photo Shop Big?). As you may be able to ascertain from the images below, with the right hand framing of a scene being at least 2000 pixels wide, the entire map would be more than 20000 pixels by 9000 pixels to satisfy the requirements of a cinema resolution (2k) artwork. I therefore decided to strategically split the sequence up into overlapping segments that could be handled during compositing. Those elements could than be mapped onto a 3D surface and make up the path followed by the camera. As most transitions were cuts, rather than camera moves, the transitions could be hidden and the whole sequence looked like one continuous move on a giant map. I hope the sequence of images below illustrate the setup of the background and the arrangement of the individual scenes. No paper was harmed in the making of these artworks, it's all digital.
