When you mention wedding venues in the Florida Keys everyone wants to see a white sand beach, tropical flowers as an accent, and the Caribbean waters. As a wedding photographer in Key West, I am afforded the luxury of getting to work at all of the venues, and see what each one has to offer. I think that is part of the draw to being a wedding photographer, as I like to create a completely different image at the same venue, time and time again.
For me an ideal venue is one that has water, tropical greens, and an open area to shoot from. You can have a wide open space, which affords you functionality, but it needs to have substance. Now take that same open space, add in some foliage and voila. With the right photographer, the components will blend, and the magic will happen.
