Abstract. We describe a method for computing theoretical photometric amplitude ratios for a number of modes of nonradially
pulsating subdwarf B stars in both SDSS and UBVR systems. In order to avoid costly solutions of the non-adiabatic non-
radial pulsation equations, we have adopted the adiabatic approximation. We argue that this is a valid approach, at least for
