I am not advocating the use of 400TN in its present form. I am saying that chromogenic films could be tailored to give more desirable printing characteristics on proper Silver-image B&W paper, and to hell with printing the negatives on colour paper.
PMK is an outmoded, hit-and-miss, minority appeal process that's only suited to the dilletante enthusiast. C41 is cheaply and widely available, and far more consistent.
OK? Now everybody is equally offended. ;^)
