Although the only way you're going to see grain when printing a Kodachrome
25 transparency is with a good grain magnifier.. Once you make even an
16x20" print a magnifying glass helps to see it.
On the other hand from blow ups from Kodachrome 400 no problem looks like
Tri x in D76 1:1. Not magnification necessary.
