Ok, so weddings are A LOT of work for everyone. For a photographer, it is a hard day of running around, making sure you capture everything you can and making sure you make the bride and groom VERY happy. Did I mention that we have to do all this and try not to be seen. We try our best to be a fly on the wall and capture every perfect moment.
We make sure we have top of the line equipment because our equipment goes through a lot during a wedding. I don't know how many times we have to toss our cameras in the back seat of the car after a ceremony and rush off to the reception.
