dmg, you are so right on almost every point! I had to buy one digital camera early on, (Canon because I already had the lenses that fitted) but the aspect ratio (1.6x) ruined my whole perspective. I never got used to it, that is why I always had a film camera with me, as well. Early in June I bought an Eos 5d mark II (had to sell part of my cigarette packs collection and some books and records, as well) and now this problem is solved!! But the film camera stayed on! I was lucky to be given in 2007 an Eos 1V Canon film camera, and it was really 100% full frame, water resistant and absolutely enjoy working with it! For the ones not aware, most film cameras had an issue. What you saw in the view finder was the 95-98% of the image that was depicted on film. Then most of the digital models -up to semi pro- could use the some lenses as the film cameras, but there was a 1.6 crop factor. see:
http://www.kenrockwell.com/canon/1-6x.htmI buy the 30m roll, usually from the USA and load it myself, so it is a bit cheaper than buying a single roll at a time.
I used to take photos all the time, and yes, knowing that you have a film limit of frames to take, was a good way to get into the photograph, discipline your eye and finger and try to do the best out of every frame. But everybody has to make his mistakes. It is not working by seen other people's mistakes. So you take photos just to see how it looks, and after years you can say, "what a load of crap". But the seeds are there, you can't avoid taking these photos. Now it is a bit easier and a lot cheaper to take photos, and the only limit I have (and it is working) is the time I have to even see the photos I take! So knowing I will have to spend hours on ending just filing my digital photos, make me hold back from taking just snaps!
Even though I use it rarely to have an opinion, from what I hear from other photographers, they shot in RAW (which is by default colour) and then they turn it into B&W and it works OK. There are many programs around (some new cameras have it on as well) that can give your photo the look of almost every film there is! I haven't tried it, but I have seen some results and they were convincing! I saw the M camera but I really don't get the idea behind Leica's Monochrom, but if it gives results, who am I to say anything! I mean all films and cameras (even b&w) are panchromatic. This means that they can capture the wave lengths of the colours, and the b&w films translate these wave lengths in grey tones. From the view finder you see colour, so it is a mind thing, trying to see things in b&w, or even imagine how they would look in b&w.
I saw The passenger when it was re-released in the late 90ies, and I paid attention especially on the well known seen. I still prefer the Blow up film, and I was a bit disappointed with Zabrinski point. Still have many Antonioni films to watch! I will look for the other ones you mention!
