1. A machine-implemented method of graphics processing, comprising:
for each of a plurality of low-level probe positions within a scene, determining directional lighting representations at its position by incorporating data from one or more directional representations of lighting for first probe positions within the scene;
using the directional representations of lighting for the low-level probe positions to determine lighting indications for visible surfaces of the scene for pixels in a frame; and
shading the pixels in the frame in accordance with the determined lighting indications.
