I was just looking through our photos from my daughter's Bat Miztvah and I just had to give a shout-out to the photographer, Yehoshua Halevi. Some of his work blows my mind. Aside from an overall excellent job on both formal and action shots, he did two things that really surprised me: First, he managed to capture the emotion and nuances of... people giving speeches! He captured facial expressions of the speakers, posture shifts, and reactions of onlookers – all of which tell the "story" almost as much as the speeches themselves.
Second, he managed to shoot a large collection of dancing/action pictures without ever getting in the way. None of us recall having him shove through a crowd, break up or reposition anyone, or interfere in the way that photographers often do to get "that perfect angle."
In short, if you need a photographer any time soon – and you only get one shot at this – you'll be in excellent hands, get a fabulous result beyond what you'd imagine, and all at a perfectly reasonable price.
