I speak not about other films with brand-names, but I speak about a low speed microfilm like Agfa Copex HDP, it has even in the best low gamma developers no overexposure-latitude, because this emulsion was changed in 2000 from Copex Pan to Copex HDP with enhanced gold-sensibilisation. The reason was, that a lot of not well-trained users were working with too strong used developers, and speed of developed films was lost. A higher gold-sensitated film in bad old developers will not loss its speed. But too much gold ruins the latitude, not for documentation, but for a (not from the emulsion people planned) pictorial use. Microfilms have always a low silver-coating, you cannot get higher density than Dmax = 2.2 Only microfilm are not an answer for better films in a better future of AgHal-photography.
Thats the reason, why Gigabitfilm use films with higher degree of monodispers distribution than microfilms, that means, there must be a better resolution than in microfilms, when you compare in the same wavelenght. And we use films with more silver on it, for a Dmax = more than 4.0. Now you can make diaslide. And we use a sensibilisation up to 700 nanometers, because nearly 30 % of all users had used in past red or orangefilters for more dramatic landsapes.
I found it very well, when Rollei will bring the TechnicalPan successor in 120 rollfilm. Gigabitfilm try to build up a production for the 320-film, a film in the length of the 120, but without paperbackside for better planety. This 320 is like a 220 except, that the film will have the lenghth of a 120. Since two month I am waiting to get the first cutted rolls for internal testing.
