We present a few examples among cool white dwarfs showing the effect of field strength and geometry on the observed optical spectrum. Modelling of hydrogen and heavy element spectral lines reveals a range of uniform or markedly offset dipole fields in these objects.A.K., L.F. and S.V. acknowledge support from the Czech Science Foundation (15-15943S).
