Something that I (and probably every other experienced wedding photographer) frequently encounter is the question, “So why should I pay you $XX when this other photographer will only charge me $X? More often than not, the other photographer is a “newbie” to the profession.
There are a LOT of answers to this question, but this blog post does a great job of answering – “The Broke-Ass Bride’s Guide to Newbie Vendors”. If you are considering hiring someone for your wedding who has little or no experience, I would highly encourage you to read this.
