Dear Roger,
As they say in the islands, "True dat" 🙂
My parents, for example, never lived together before getting married - fancy that.. they were together for 42 years until my mother died in 2006. That's just one example. There are, I'm sure, plenty of others 🙂
That said, going back to the OP's query and the debate over whether $2,000 is a lot of money for wedding photography. Ya know, there are a whole whack of people out there *points to beyond the RangeFinder Forum* that think paying $7,000 USD for a full frame digital camera body is ridiculous when you can get a perfectly fine full frame digital camera body for $2,700 USD or even cheaper if you don't want "full frame" (which a lot of people not in the know would say "what's 'full frame'???").
So, similarly, there are people that will say that $2,000 truly is a lot of money (either because money is tight for them or they're frugal or they just don't know any better or they do know better and they don't feel anyone/thing is worth that $2,000) and conversely there are those that would drop $10,000 for a wedding photographer because of the exact same reasons.
Either way you slice it, the end result is, the bride and the groom MUST BE HAPPY with the choices they make. Whether it's to spend $2,000 or more or to just get someone to shoot it "por nada". In the end it is only the married couple that matters and as long as they're satisfied with their images, then everything else; price, type of camera, name of the photographer, etc. etc. etc. is moot 🙂
Cheers,
Dave
