On distingue deux termes : le grandissement (g) et le grossissement (G). Le grandissement est également appelé grandissement linéaire car il est calculé à partir du ratio de hauteurs ou du ratio de largeurs. Le grossissement, pour sa part, est également appelé grossissement angulaire. 4, record 1, French, - grossissement

The center of perspective is that viewpoint at which the angular subtenses of points in the picture are identical with the angular subtenses of the original points in the scene, at the camera lens. Viewing a picture from too far away results in an excessive magnification of near points compared with distant points. 2, record 3, English, - perspective%20distortion
