The only less than perfect reviews I have seen were in our resort search. For photographers, and other vendors I also notice 5 stars and the rare 4 stars.
Do your own research by visiting the photographers’ website, see if you like their work first.
Check to see if they are involved in more than one wedding website, and crosscheck the reviews.
The same review in two different sites could mean a fake review ( A tip for when I was searching for a nail salon ). Visit their facebook or twitter if they have one, and see the types of comments others leave there. Avoid a photographers that are not willing to be flexible for you, shows hesitation or speaks ill of other vendors. Best tip is to send the photographer an e-mail to see how well they will work with you. Try to reach them by phone or meet them if even possible.
Our photographer is from Toronto and will be taking our pictures this week. You can try him. His name is Enrique and the company is Decordova Photography.
