Quote from Tom:
. . .If you can shoot the same film in all lighting conditions, then everything becomes much easier at the printing stage, because you know what to expect, and in my experience that saves me a lot of wasted (expensive) paper. If you don't like Tri-X grain, that's too bad, but that is again not what the OP was asking about. It doesn't actually matter what film the OP is using, or what aperture they use, because it's a question that applies universally regardless of materials used."
Yep. I get it now. Clearly THAT must be your Zen, the underpinnings of your photographic philosophy. While I'd strongly recommend you try another film of a lower ISO simply for thrill of doing something different, what you said above is your opinion as opposed to mine. And I have to say that generally, it leads to stagnation and a body of work that looks, well, (at least from a technical perspective) pretty much the same.
So, I gotta ask; How can you possibly learn anything when you don't try new approaches to the same issues? In essence, that can't lead to "Good art". It seems to act as a barrier toward expansion and more complete use of the mind and the camera as a tool of the mind and that in turn, I think, obviates excellence simply by leading one to act strictly out of habit. To me, that all leads to boredom and would lead me to question why I chose a profession so intimately associated with art and finding new ways of visual expression along with creativity and a universe of technical variances. And yes, that's my opinion too. yet to some, mind boggling I'm sure.
