I recovered after a few days thankfully. Yeah the camera (Nikon AW100) did a good enough job but it was touch and go to be honest as I had been battling with a minute amount of water ingress all week that when the camera warmed up due to use underwater the temperature difference over the lens caused internal fogging, massive pain in the backside, it also ruined a good shoot when I went paragliding, caused by reduced air temperature and pressure whilst dangling high up in the air. Had to cook the camera in direct sunlight with the door open and a silica sachet in the battery compartment the day before I did the whale sharks, and crossed my fingers that one battery would last the shoot without me having to crack the door open that I had sealed up with beeswax for double measures (so glad I brought that with me).
