I just spoke to Dick Arentz about the question of UV blocking in Tmax 100 film. After being alerted to the potential problem of this film, first discussed on this list, he tested Tmax 100 with Pt/Pd and confirms that the effective UV blockage is approximately three full stops.

What is it that causes this blocking ? Surely if the film is properly fixed and the magenta cast removed should it not act like other film ? Perhaps I am missing something !!
