Indeed, Thomas. The main differences between films are granularity, and within a speed category (and grain type - ie tabular vs non-tabular) those differences tend to be pretty small. The gradation (tonality) characteristics of most current films in the ISO range of say 100-400 are very similar overall with few exceptions (such as TXP 320). Actually, in a "blind test", barring extreme procedures, I'd bet most people would be hard pressed to tell the difference between say TX400 and HP5. I often wonder how/why it is people are so emphatic about certain films vs other films when they can never even state clearly what the differences are. You get a guy saying one film has incredible tonality vs another film which is terrible, when in fact the characteristic curves may be virtually identical. Strange how that works.
