Verichrome Pan lived a long and to some a useful life. To others of us VP never lived up to the claims of how wonderful it was supposed to be. I agree that it was intended to be "the" film of choice for box camera users. I believe it did a satisfactory job in that category, but many of us were not at all happy with it for repeatable professional use in top of the line medium format cameras. Panatomic X was everything that some folks believe VP to be a faster Pan X and was very similar, chemically it may have been, but it is simply not true that the two emulsions worked equally well.
VP seems to have become one of photography's myths and is being touted by some to have been a wonderful long scale film. I and many others did not find that to be the case. There were several films available at that time that gave superior results to the best that VP had to offer. Super XX for instance, Ansco had a great film named Hypan, later Super HyPan or something like that. Gevaert had some wonderful films that did everything that VP was supposed to do, but diden't. Believe the myth if you want to, but I know better!
Happy dreams of of films now long gone! Thank the Lord that Kodak had the good sense to remove VP from the market when it did. Now I'll bet the flames begin!......
