This has all been debated and discussed to ad naseum many, many times. Perhaps what he is saying about one specific paper is true; I don't know; I have never used Oriental Seagull in any of its iterations. I was at first skeptical about the Tri-X reformulation but I have yet to be able to see any discernible difference in the prints between old and new. It's still a great film IMO. It's hard to see how a conventional silver film can get much better than the current FP4+. The new Tmax 400 is drawing rave reviews from everyone who's reported on it so far.

What we have seen is a drastic decline in the variety of photographic products available to the user. The blame for that lays strictly on the activists for non-silver photography.
