This is a very good thread. I don't want to showcase my professional work, for various reasons, but I can tell you from my perspective, family and friends often have the very best chance at getting some truly great shots at weddings. I know I am in the minority of wedding photographers, but I like and even actively encourage other shooters to get the shots they want, for many reasons. One, everybody has their own vision, I just happen to be paid for mine during that day, and I feel that I should not hamper the vision of perhaps a family member or close friend. Two, photography is fun, and weddings are a great time to shoot, and if everyone is having fun the shots are easy to get, there is absolutely no reason for me to be the cause of stress at a wedding and I know I'd get a little bent out of shape if 'the pro' told me not to shoot if I was a guest. Three, if I'm as good as they pay me to be (and humbly, I am) then I should be able to get the shots I need and want that are unique to my vision and style of shooting. Fourth, coming from a photojournalist background, I'd often have to get a shot with 3-4 other still guys AND 4-5 video crews (complete with eyecandy reporters tethered and in the way). So, a few Uncle Bobs (wedding term for Family Friend With Camera) are not going to spoil my day.
Not to say it can get a bit funny at times. I had a wedding where there were 75 people and at least 90 cameras, it was truly and utterly ridiculous. Instead of getting annoyed and 'controlling' the situation (which I know from professional 'gossip' is how most of the area photographers handle that situation), it made me really tightend down and get shots that were far outside the norm of what everyone else was shooting. So, I took more riskes and pulled out some techniques from the deep closet of Creativity. The couple Loved the shots, because they had seen all the other family and friends shots and I showed them something different to their day.
Many years ago I when I was still doing pj, a good friend of mine got married. I really wanted to shoot their wedding, but the wife said that she got the very best hottest guy in the area (I was traveling to the wedding) and this guy was such a poser. Missed the *easy* stuff, he spent most of the ceremony prancing about with a Mamiya 7 like it was a magic wand of gold and Not Pressing The Shutter, on the wrong side of everything, and just Blew It during the reception. I was mellow and just got the shots that went my direction, and did my thing low key with a M4 w/35mm Summicron and a Fm-2 with a 105mm and scored the best shots of the wedding. I saw the other guys work later in the album and it was all really below average, I'm glad I gave them some matted prints for the wall, which they display and look at every day.
The point is, when I saw that guys working method, style and 'attitude', I thought, 'I Know I can do better than that guy at weddings', and so I did. But I never forget that I was once not 'The Pro' yet got good shots for a friend, and that meant a lot to me and my friend and our friendship. As well, that event keeps me humble and low-attitude, I certainly don't want to be the one with the 'Fairy Wand of Gold' who misses easy shots.
