The HDR Manifesto
In a 1997 interview with David Bowie, Guitar Player Magazine asked, "Do you ever seek out a guitar that is rife with associations?" And Bowie replied, "Maybe something like a Rickenbacker 12-string, a guitar that almost has a manifesto attached to it." He was talking about the fact that you cannot pick up a Ric without playing jingle-jangle arpeggiated chords on it, like the countless '60 and '70s hits that made that guitar famous (Ticket To Ride, Turn! Turn! Turn, Mr. Tambourine Man, If I Needed Someone, The Waiting, etc.). Guitarists - try it, I tell you it's impossible!
HDR photography has a manifesto too. And in section IV, On Subject Matter and Clichés, it states that all aspiring HDR photographers must attempt at least one urban skyline shot. It also says something about landscapes at sunrise/sunset, but that's a post for another day.
