There are probably 2 different 'groups' of photographers. Those who shoot destination weddings as a business and those who like to take a trip or two every year, have the trip paid for and make a couple hundred bucks while they are there.
The first group is probably better prepared to work for you. they know the area, the people, the language, awesome locations and secret spots. This is of added value to you and will ultimately result in better photos. If photography is important to you...and why would it not be, it's all you will have in a year, 10 years, 20 years then the question is not 'what are others paying' it should be 'what are YOU willing to pay' for a photographer that is going to rock your world. Because photography is so subjective you should find one that fits your style best. Classic and traditional? Edgy? Creative?
Ask yourself this...
If a photographer who normally charges $3000-6000 for local weddings, WHY are they offering coverage to you for $500 or $1000? What are you missing out on?
Good luck!!
