I agree that you 100% have to use the best equipment possible and know it inside and out. And of course RAW won't fix everything, I would hope if someone was going to shoot a wedding they would know that but, I should know better than to say that in the digital age.
I was very young, 19 when I started in the photography business. I was working at a portrait studio and I had just come into work when my boss was helping a woman who was in a terrible car accident, pretty much her entire body was in a cast. Nearly everyone in her family died. She wanted reprints of photos from a huge family portrait we had shot a few months earlier. (thank god we had them, I think we only kept them on file for 6 months) I didn't shoot it, sell it and this was my first time seeing it. Sadly the images looked like they did not come out that well. They had to do a lot of creative cropping (120 film days) and since it was a group shot of about 20 people there was a lot of shots with different people blinking or kids not cooperating.
That has always stuck with me, that any job like that, especially a wedding or large family portrait is pricelessly important. This is also why I only shoot small weddings and people know what they are getting. They won't be getting high fashion modeling bridal party shots, and a lot of people do not want that. They just want a good photo. Properly exposed, cropped and people posed nicely. It is also a lot less pressure when its a small wedding and I have less people to take photos of, more time (not really, but its worse the more people that are involved, it always means someone is late) and I'm a lot more relaxed!
to each their own, I just prefer to take on smaller jobs and keep the stress to a minimum, the stresses of a large extravagant expensive wedding is not worth the monetary pros to the health consequences cons....
