I took a picture of a passing train with my iPhone from the side.
Scan the train as if you were scanning a film.
Since it is a vertical video on a smartphone, I will post a short video as the main one.
Please use it to temporarily stop and observe the equipment under the floor. I think that it will be a reference for model making.
From this video, if you cut out still images one frame at a time and connect them well, you can create a horizontal still image like a banner photo (*).
It takes pictures like a slit camera that was popular in the old film era.
*The sky and clouds in the banner photo are cut out and synthesized.
