The photons are not affected, but space itself is. The idea of GR was, that gravity is actually an effect of 'curvature', which is itself caused by gravity. What gets curved is actually the 'axis of time' local to a certain part of space. What we call 'space' has a certain (geometric) relation to the axis of time, if we regard the axis of time as imaginary and the axes of space as real. Then we have i as a factor, by which time gets multiplied and what gives us three real axes of space. This space is therefore depending on the direction of time. Curvature of the axis of time is actually an acceleration in a space-time diagram, which usually has one axis of time and only one of type space. Now this can 'curve' and we get gravity, which is a force, that results from such curvature. Now light ('photons') pass through such a distorted space upon force free straight lines, which are actually curved in spacetime in presence of a gravitational field. This pass is NOT curved by gravitation, but by curvature of space. .... TH
