Anything with the word "Negative" in it may seem to rule out slide film. Likewise "silver" may rule out some processes that will be of interest. I don't like "Non-digital" either - *we* were here first, dammit! :-)

Out of those mentioned, "Traditional Photography" sounds about the best, but how about a strap line (similar to B&WP's "Any colour as long as it's black (or white)") to spice it up a bit... ...something like "Tales from the Dark Slide" or "We like it wet!"
