Is there anything you have read in the discussion that would shift your recommendation from TMZ to a 400 ISO film? I have *one* roll of Tri-X and two rolls of TMZ. My baseline is to shoot TMZ. Honestly, now that I have it, what else am I gonna do with it? But if you changed your mind, I'd rather know.
Not really.
But whatever you choose, you will get a result that contributes to your accumulation of experience and the refining of your preferences - the 1000 rolls and 10,000 hours referred to by @koraks . While that may be a bit of shorthand, it really has a huge kernel of truth in it.
And if you chose something different next time, you will get a different result. The result you prefer will be partially as a result of objective criteria, and partially as a result of subjective choices. And you could very well get two different results out of the two different choices that please you in different ways.
I've currently got four prints matted, framed and ready for transport out to the gathering point from which my Darkroom Group's group show will be organized for its opening in September. For fun, the four prints each come from different rolls of film, using four different formats of film, exposed using four different camera systems, each of which originated in a different era.
I was able to essentially play like this, because of the experience that preceded it.
Hope you have fun during the visit, and are both pleased and informed by the photographs.
