Sounds like a diver who can't be bothered unless you have 100'+ vis and calm seas.. There is some really cool shots in that video.
Re the 10' dive.. Actually its pretty easy to get 20' at BHB, but who's counting. And not only is it a great dive, but a nice place to do shake downs. I recently had my three kids down to S.Fla for two days of boat diving. We timed it so we could hit BHB before the two days of boat charters so they could confirm buoyancy and weight needed for salt water before going out on the boat.
Speaking from experience.... photographers and videographers are terrible buddies. Terrible.... I wouldn't blame anybody for not wanting either as a buddy.
Ummm.. generalize much? I have had terrible dive buddies where no cameras were involved.
I would agree that an overly camera-focused buddy can be rude and detract from the enjoyment of the non-photog. But, it depends a lot on several factors.
I had a recent dive, where I knew in advance my buddy wanted to shoot some video. We talked it through and even agreed on timing and lead/follow protocol so he could get shot of me navigating a specific restriction on the dive. We had a dive plan that we were both comfortable with and we stuck to it. ..NO problem.
As far as the OP.. I think he took reasonable steps. I like that he had the FeauxPro on a recoil mount and seemed to realized that pic taking was definitely secondary to buoyancy and trim.
Now for how to deal with your significant other.. I have found "Yes Dear" to generally be the best course of action.. But this might be a golden opportunity for you to double check boundaries and level of commitment..
