The whole wedding business is ridiculous, imho. Inflated expectations and huge spending with venues, wedding planners, food, bands, costumes, rings, photography and whatnot for something very mundane. I hear that people actually get a loan to pay for their wedding, which is not a good start for a marriage.
I am not anti-wedding, anybody can get married in the low earth orbit if they want and can afford it, but I can and do understand that some reality is seeping into new couples' minds. I've also heard that Instagram and the like are changing the expectations of what wedding photos should look like, hence many couples are actually happy with a ton of phone pictures.
I believe these are "fashion" things. The trend now is the phone and Insta, but I'm sure 10 years from now it is something entirely different.
Even in this forum we get time to time posts asking: "I'm shooting a wedding the day after tomorrow. What lens should I buy?" This signifies to me that the couples want something entirely different than the classic professional wedding pictures. The customer is always right.
