The camera focuses on the foreground and moves the lens according to the scene of the image (which can be set as a stationary person, object, or open ground, with pedestrians and moving vehicles), while the background is the complete outline of the building (such as high-rise buildings, factories, etc., maintaining the initial stationary state). The scene begins with a calm sense of daily life for a few seconds, followed by a sudden violent explosion in the background building - flames carrying orange red light clusters burst out from the inside of the building, and wall fragments, smoke, and sparks instantly shot out in all directions, creating a highly destructive visual impact. At the same time as the explosion occurs, the camera produces obvious but controllable vibrations with the shock wave (the amplitude is sufficient to reflect the impact force, but does not deviate from the main scene), and the edges of the picture can have slight momentary blurring or shaking effects, enhancing the realistic sense of presence. After the explosion, the building debris collapsed or burned in flames and thick smoke, and the camera gradually stabilized back to a fixed state, continuously capturing the static contrast between the background explosion aftermath and the foreground.
