Looking back at it , it recalls me the decals I used to do when I was a child . Although it seems quite simple , just look at the restore job there was to do to make that 20 000 pixels panorama a seamless composition covering a 360 ° angle of view ( pic B , C , D , E illustrates in details before and after matte work ) . It was a long photoshop task to blend all the source pics together . Compared to that , adding all the animals was a funny and easy game Pics at the bottom ( 1 , 2 , 3 ) are stills from the final shot in wich the camera revolves around a visitor walking in that weird zoo .
