What should I pay attention to in underwater photography in Maldives?

I suggest renting an underwater camera online. It is not recommended that you buy a common waterproof sleeve and shoot underwater with a SLR, because the common waterproof sleeve is easy to get into the water and damage the camera, which is not worth the candle. In addition, be sure to read the usage of the camera carefully in advance, such as not opening any cover underwater after diving, and changing the battery before the camera is dry. In addition, it is recommended to soak the camera in fresh water 15 minutes after each snorkeling to avoid the camera being corroded by excessive salt in seawater.
