The starting frame, has the camera up close and a large field of view. The 7 lattice is in black, and the grid lattice in red, to compliment the intensity of the fish-eye lens effect.
By the last frame, the camera is pushed away from the structure and adapted to a flat infinite focal point. The 7 lattice blends to a ‘pure’ white, and the grid lattice to a gentle sky blue at the points, with its intensity varying with height.
