Hi Bill,(posted 9151 days ago)despite the fact that my editors hate grains, I love the large grainy effects in my personal black and white work. HP5+ and Rodinol has proven to be a good combination for producing large but lovely grains. It may not be for everyone, but you may just fall in love with it. If you do prefer the fine grain, however, I would agree with the previous reply that Xtol is the choice. When I need fine grain with HP5+, I use Xtol at 1:3 dilution. Good luck and welcome back to the b&w world.
