Hi karik,
I think any of us who've tried to take more than just snapshots at a wedding, myself included, can understand where you are coming from. Indeed I'd advise any couple to engage the services of a professional photographer if the budget permits as, from my own observation, there are so many things to think of and plan for and a handful of things that, if they get missed or messed up, could end up spoiling the day. And that's not meant to impugn Chris in any way as I have no way to know how well he might do.
But, and it's a big but, I think your level of activity and generally abrasive tone in this thread doesn't sit too well with our friendly CameraLabs spirit and I'm offering that opinion as a Moderator here on the forum. Much better to state your opinion clearly and, if need be, at length in a single post and try and avoid effectively trying to shout down everyone else by sheer quantity of posts, some of which resort to name calling which is in direct contravention of our
forum rules. Please consider this an official warning.
@Chris I know my limits so I won't offer any advice in an area which is clearly out of my expertise other than that you might want to avoid, if at all possible, taking on the role of prime photographer without prior experience. If your friends can afford to get the money shots done by a professional, even if they can only afford one of limited experience, then that puts you in a much more comfortable position as, dare I use the phrase in the light of what's been said earlier in the thread, "back-up photographer". Sorry to be a bit negative and whatever you decide "Good Luck".
Bob.
