The challenges experienced when trying to photograph a turtle underwater are plentiful. In addition to needing cooperative turtles, clear water, sun, and a water proof camera are required. Additionally, you must be a proficient enough photographer to be able to operate said water proof camera without using the touch screen (or really being able to see anything you are doing).
I bought my second digital camera well over 10 years ago because it was 1) really small and easy to carry around while tandeming in exotic locations and 2) because I thought I would be coming to Hawaii more often and a waterproof case was available as an option (albeit at a cost higher than for the camera). As it turns out, we did very little snorkeling in the last 10 years, and by the time we moved here the camera/case didn't seem to work very well. Enter digital camera number 4. As I alluded to above, it is very difficult to use underwater--mostly because most small point and shoots no longer have view finders.
But enough boring stuff. Please enjoy a couple of pictures (and a short video) of some mostly friendly sea turtles. If you turn up the sound on the video, you can hear some humpback whales singing off in the distance.
