I'm not sure I am following that. Are you saying that 100 asa b&w print film has a different speed than 100 asa transparency? or that transparency is best when it is under-exposed. If that is the case, why isn't a 100 asa transparency rated 80 asa? Or have I completely missed the point?... a very likely possibility
