Some people are more concerned about saving money that they fail to realize the importance of hiring a professional photographer. Here are a few images I located on the net that represent the difference in quality verses doing it yourself (saving money).
Please note: If hiring a photographer for something as precious as first baby pics or your very special wedding day, view said photographers body of work first. Many photographers today have websites or online portfolios where their best work is displayed publicly. This allows viewing from the comfort of your own home, thus increasing the decision to book an appointment or continue your search. I believe the better you are informed before said event, the more likely you'll enjoy the ending results.
