Parallax is the apparent shift in the position of an object when it is viewed from different angles or positions. It happens because the observer’s viewpoint changes. For example, when you look at an object and move your head side to side, the object seems to move against the background. In astronomy, parallax is used to measure the distance of stars. In photography or web design, it creates a sense of depth when the background and foreground move at different speeds. #foryoupage #aviationlovers
