I re-read all of the posts, and I couldn't find any remarks that disparaged the OP's ability. All of the skepticism centered around the potential folly of accepting a job (as Liza said, "someone's wedding, for God's sake) without even the minimum equipment. Furthermore, I would imagine that there are many accomplished, technically adept photographers with many years of experience who would not accept such a contract merely because it is, often, a one-shot, no-second-chance deal. The father will only walk the bride down the aisle once, the rings will only be exchanged once, the groom will only lift the bride's veil once, the first slice of wedding cake will only be cut once, the bouquet will only be thrown once, the groom will only dance with the mother of the bride once. If the photographer's equipment and ability and experience are not up to the task, the moment is lost forever. A great landscape or portrait or urban or sports photographer does not, necessarily make a great wedding photographer.
