Above is a link to an article about a particular woman who was infuriated at the notion that a photographer has the gall to charge her several thousand dollars to photograph her wedding. The original craigslist posting can be seen there as well as a sufficient article below it that discusses what exactly it means to shoot your wedding. If you continue to haggle the ability of professional photographers to make a living in favor of amateur hobbyists soon that is all that you will end up with in the industry-amateur hobbyists.
