One summer a very long time ago I photographed for a summer theatre. The theatre management didn't like grain much so I switched to Microdol-X and replenised it as I went along. The grain got finer and finer. I read somewhere that the sliver that got left in the developer got deposited on the new film acting almost as a physical developer. Sodium sulphite acts as a silver solvent. Back in the 70's Bill Pierce wrote some articles where he told of using Rodinal with the sulphite solution like that recommended for FG-7. The theory was that you got the best of both worlds, great grain and gradation.
