Timelapse was taken in the time frame of 2 weeks while the ship transit from Pacific Ocean through Japan Sea then South China Sea.
The weather and sea conditions were very crucial and sensitive in terms of producing clear images since the ship (acts literally like a motion tripod) is constantly moving, and a moving tripod is not idea.
More than 70,000 images were taken, but only 9000 were usable, then later edited into this.
