In night street photography, how does anticipating subject movement specifically aid in capturing sharp, candid moments in very low light conditions?

Anticipating subject movement in night street photography significantly aids in capturing sharp, candid moments in very low light conditions by enabling the photographer to prepare technically and compositionally *beforethe decisive moment occurs, thereby circumventing the inherent challenges posed by limited available light. Firstly, low light severely hampers a camera's autofocus system, making it slow and inaccurate to acquire focus. Anticipating *wherea subject will move allows for pre-focusing, which means the photographer manually or semi-manually sets the lens's focus to a specific distance or area *beforethe subject enters it. This bypasses the need for the camera's autofocus to acquire focus in difficult conditions, ensuring the subject will be sharp when it reaches that pre-focused point. A related technique is zone focusing, where the photographer sets the focus for a specific range of distances, such as from two to five meters, and then uses an appropriate aperture (the opening in the lens that controls light and depth of field) to ensure that anything within that pre-defined "zone....
