I very much like the pic of the Halichoeres wrasse. Well done.
Wow! Those look nice. The trigger in the first shot is just devine! There appears to be some strange artifacts in the black surrounding the subjects. Maybe its my screen?
Aaron could you possibly make a video showing how to achieve the black background using photoshop. I'm sure it's via layers and mask I've tried but my attempt don't come out as clean as yours, seems like your good at not only photography but at post processing too, a pretty lethal combination lol
This was the way I mentioned. I may have to touch up some, bit it works pretty well.
It's very easy to have a black backround when using a flash. Just experiment using lower apertures, (higher numbers).
