I'm going on a Gulf of Mexico cruise later this month and am looking for creative or must-try shots for the ship. I don't want to get home and realize I missed something. I'm consider renting a 7-14mm but only if I have some solid ideas to justify the cost. I'll have an E-M5, focal lengths from 12-150mm, Rokinon fisheye, light tripod and Gorillapod, a good flash and a GoPro. I've been searching images on Flickr and Google and have a list going, but any suggestions are appreciated.
