I am wondering if somebody can tell me about using the Kodak TechPan B&W film. I have been working with Velvia exclusively in 4x5. Recently, I bought some T-M ax 100 to start to dabble with, although I have not developed any of it. I know that the T-Max is an excellent film, but I am curious what are thew advantages of the TechPan in terms of tonality or other qualities not readily apparent. I am only going to use it as a continuous tone film. Thank you for your responses gvl
