2. Ok, you're right. Some films will certainly outperform some digital. But, the new MF backs will shoot 13-15 stops as well, so who wins? I'd argue that, on average, digital trumps film. I've shot mostly velvia (the most popular landscape/wildlife film for 30 years?) and provia, and those can't compete with even my 3 year old dslr. (see http://www.clarkvision.com/articles/dynamicrange2/ for tests done with an 8 year old dslr)
3. Get a color checker (http://xritephoto.com/ph_product_overview.aspx?ID=1192). No filters necessary, and precise color no matter what lighting conditions. And, you'd be able to eliminate one of those miserable fucking peripherals.
FWIW, going digital has tremendously simplified my workflow and allowed me more shooting time with less dicking around with equipment time, and much better quality prints (and I make really big prints). Cheers.
A professional is probably only going to use film these days if they want a specific effect; say, infrared, or sometimes people fart around with Holgas and call it art. For an amateur, the $20,000 digital back that can compare with a 4x5 with some decent lenses costing a tenth that much is a much harder sell. And that's pretty much where I sit; I'm not going to spend $50,000 on a top of the line MF outfit. I might spend the $1.2K for an X-100, though, still mulling that over. A couple thousand buys a lot of film and developer.
