Tri-X

So has the Tri-x emulsion changed so much since I last used it 35 years ago? The old Tri-X negs I still have - have a more pronounced grain. I was using D-76 at that time. The new ones are in Ilfotec DD-X and have much less pronounced grain. I did several 11 x 14's from the Tri-X / Ilfotec and was surprised that you had to look pretty close to see the grain. Or it could be I still had my contact lens in. Oh, there are always variables - even in the film world.
