A photometric analysis of the sub-structure of a granular light bridge is performed. The light bridge can be resolved into an assembly of small grains embedded in a diffuse background. Irregular motions and lifetimes of these grains were measured. Their origin and the decay is similar to those of granules. The observed phenomena represent convective motions.
