Why the obsession with setup?
I have always thought that the hardware is only a means to achieving one's vision.
I am an olympus shooter, betting on the future of the four-third system. Depending on which camera maker comes out with a better camera/lenses, i can switch between the oly, lumix and leica system.
i personally think that there are not many techniques that are unique to wedding photography alone. the photography techniques apply to all kinds of photography, be it sports, editorial, street etc.
what one needs to know about wedding is what kind of shooter one is. are you a street shooter who is good and observant and apt at capturing the special/humourous/emotional/poetic moments? or are you the control freak who wants everything set up nicely so that when you press the shutter, it's exactly what you envisage it to be? or are you the glamour type whose aim is to make the bride/groom look as beautiful as possible by all means?
every style will have their own market. choose the one that represents who you are, or what you believe in, and be the best in that particular genre.
i think the best "technique" or advice is more on how one practices the business of wedding photography. ckuang has already given a very comprehensive starter. want to know anything, i think you have to serve him tea and call him "shi fu".
by diligently looking at the wedding portfolios here, i think one can learn alot of things. of course, there's no stopping you from visiting other photo forums to learn from other photogs from overseas. a bit here, a bit there, i'm sure you will learn something. gotta put in some time, no short cuts.
i am from the old school of learning, when my seniors will just ask me to look through the contact sheets and study their train of thoughts. they would answer any questions i have, and provided critique to the crap i shot.
so perhaps the threadstarter can submit his portfolios and see how it goes.
