Hi Matt,
There are some great photo ops on the Kona coast and other places on the Big Island as well. I am looking forward to exploring more, myself. I have seen water so clear in Honaunau that the dolphins looked like they were flying - not all the time but every now and then it gets really, really clear.
You are certainly welcome. I will say that the sooner you have a date in mind the better because I am getting a strong response to this opportunity....did you plan on coming alone or are you bringing a guest?
I would enjoy talking with you more about photography.
There is also a gathering of freedivers every Sunday at Honaunau if you are looking for subjects. I am on social terms with Rob White over at Blue Water Hunter, another nice guy and crazy spearo...

Lets talk more... I will pm you with my email address. That way I can send you some pics of the place.
