Welcome to Wakatobi, one of the premier dive spots in the world and home of Indonesia's best boat marina. The thing is it's totally abandoned basically and it costs nothing to stay there. Join me as I try to figure out what happened here and why...
I occasionally get that message with the card I always use in my Air 2S but the videos always come out fine. I'm not sure if it's a momentary hiccup or what but it doesn't affect what I'm shooting. It only happens once in a while.
Yes, that's what I'm thinking.
Is it stored in a case or bag? If so, try tossing in some type of rechargeable silica gel packet (like this one) to try capturing any moisture that might be trapped inside of the camera.
