parallaxes
Positional shifts observed
Parallaxes is the plural of parallax, the apparent shift in an object's position when viewed from different angles.
Hold a finger close to your face and alternate closing each eye—the finger seems to jump against the background.
Astronomers use stellar parallax to calculate distances to nearby stars.
In photography and optics, parallax causes the viewfinder image to differ slightly from what the lens captures.
