Nonradial stellar oscillations cause brightness changes, which result from temperature, ge- ometrical and pressure perturbations. The observed values of photometric amplitudes and phases are determined by competition between those three effects whose contributions depend on stellar parameters and on pulsation mode. I compare the importance of the individual contributions towards the light variations as a function of the spherical harmonic degree, ℓ, and mode frequency, ν , for β Cephei, Slowly Pulsating B-type and δ Scuti star models. All computations are performed in the framework of linear non-adiabatic theory of stellar pulsation neglecting all effects of rotation. Static plan-parallel Kurucz models of stellar atmospheres are used.
