How does the camera capture a light source a trail of light instead of just a point.
In: Technology
Think of it like all the frames in 2 seconds of a movie combined into a single image, except it’s live so it is continuous time being recorded in that 2 seconds not divided up moments in time. A long exposure captures everything over the span of time the shutter is open. Photography literally means “light writing.” The light is like a brush that paints on the film or sensor for exactly how long you set it. The longer it exposes the more writing is done by the light on the film/sensor.
