Anyone know what the difference is between the 3-bath and 6-bath kits? Any difference in archivability of the processed film? Tone or color? Grain? The 3-bath kit seems to suggest Fuji films need an extra 15% in the first developer, does this apply to the 6-bath also? There doesn't seem to be a lot of into about the 6-bath on Jobo USA's website... I can't be the first to wonder about this...?
