The art direction was complicated since we needed the image on the bus to look perfect both with the doors shut and open. When the doors are shut it has to look like the 3 animals are in the photo completely naturally. And when the doors open and rearrange the photo, it still has to look like a completely natural photo of a forrest, just without the animals. And with the doors only opening up 70 cm. it took precision work to create the perfect illusion.
