Having seen all of the good results in this thread compared with the shot I had posted, I figured it was time to revisit the combination of APX400 in Rodinal to see how things would turn out. The result is at http://www.apug.org/gallery/showphoto.php?photo=37888 and shows well controlled grain and a level of detail unimaginable from my earlier shot, a pleasant surprise considering it was the same batch of film and same bottle of Rodinal. Maybe it just needed another year or so of ripening.
