Oh yes, decisions can be difficult. I got married last february at Dreams and did tons of research before finding my photographers. As a professional photo editor, I really wanted the wedding photos to be special and one thing I know is that you usually get what you pay for. One advice is do not scrimp on your photography budget. The photos are the lasting memories of the day and most of cheap photographers will just shoot and burn, giving you flat, dull, unedited photographs .Of course it all depends what you are looking for and how much photography is important to you.
I found Photo Souvenir ( you can find them in the vendor reviews) at the last minute and begged Renaud and Severine to commit to shooting our wedding. They were clearly the best wedding photographers in Punta Cana, by a long shot. I also liked Katya Nova's work and Karina Jensen but Severine and Renaud's work had it all for me with a perfect combination of lightning/composition/storytelling/creativity/pricing. Photographers like them in New York would cost at least 5000 US so their rates are very good for what they do and you might consider the option if it is in your budget range. I personally had the best experience and my photos are outstanding ( and I am very hard to please!). I will place a full review soon and I hope it helps.
