I like the photojournalistic wedding style, but I have to say that most are unable to capture the emotion that really gives impact to that style of photography.
I remember a few shots that have really made me feel the emotions that were present at the event. There is one shot I remember seeing that showed the bride dancing with her father. There was the sparkle of tears in his eyes as he held his "little girl all grown up" (my interpretation) for what he may have feared to be his last time. Neither was looking at the camera, and you could tell that the capture was of a very private moment between dad and his daughter. In that one shot you saw pride, love, fear and anticipation. I wish I could remember who took the picture, as it is the most moving "photojournalistic" wedding shot I've ever seen.
It's the raw emotion that sets separates photojournalistic and snap shot.
