if hf`=hf(1-GM/(R*c^2)

then as the distance becomes larger, R becomes larger, so f`becomes smaller?

I'm not 100% sure, but I think t hat when leaving the star, the photon has to get out of the gravitation-field of the star, therefore its kinetic energy has to decrease since the potential energy is rising.
