Well, considering I had no experience whatsoever, let alone time to read and read read the manual, I have now been baptized by fire into the world of HiDef underwater video. It was a trial by ordeal, lol.
First impressions:
1.White balancing makes a HUGE difference as I discovered halfway through my Puerto Galera Philippines dive trip once my task loading was low enough to actually start thinking about the videocam underwater.
2.Never take $15k worth of under water video equipment with you whilst dealing with an intermittently badly leaking mouthpiece and counterlung/scrubber that wants to flood. (all resolved by the 2nd day.
3.The flip filters want to sag downwards a tad, requiring you check and occassionally make sure they are up against the stop. Yes, you do need to zoom in 10% or so you dont' see vignetting on the camera monitor and the computer monitor, who knows what will happen on a flat panel plasma if not zoomed in 10%.
4.The macro on the 2nd flip filter worked well after I used a fine diamond wheel grinder on the outer diameter of the macro lens AND after mounting on the arm, the slight edge thickness that protruded rearwards from the flip arm. Essentially what I did was thin out the very outer edge thickness of the glass, reducing the chance of rubbing against the front of the aluminum rectangular shade mount on the lens end of the FX1.
5. Amphibico's 35-50 watts HID lights really make a difference, but lights only work out to about 3-4 feet away.
6. Due to my failure to white balance and sometimes have the color correction filter in place when I got so excited seeing REALLY cool bizarre critters, I will be forced to attempt to fix it all using Apple's Final Cut Express HD's color correction tools.
7.It is important to switch arms carrying the Phenom so one arm doesn't get disproportionately buff.
8. Atlantis Dive Resort in Puerto Galera has dive guides who will carrying your Phenom back and forth so you do not have to resort to tip #7 above.
9.Forget about having the needed handle AND the monitor on the back if you have middle aged eyes.
10. Just a regular braided mountaineering rope section with snap bolts on each ends works great, no fancy lanyard/tether needed.
11. I successfully did not scratch my dome port based upon the ample warnings here.
12. An underwater tripod is a MUST when macro videotaping 1.5mm long commensal sea urchin shrimp lest land based footage viewers get motion sick on the stationery couch.
13. Big cuttlefish get big by not letting you get closer than 4' with your videocam, whereas I got close enough to small cuttlefish I was able to gently hold them in Puerto Galera.
14. I got attacked by a big pissed Titan triggerfish, but more importantly-in true videographer style, got it all on tape from a 1st person perpective AND made his teeth miss my beloved Phenom port.
A huge thanks to all for answering all my lame newbie questions,(plenty more to come!)...your help allowed me to stumble my way through my first tropical dive with a HD videocam and get enough usable footage that made it all completely worthwhile so now I am encouraged so am plotting, er, I mean planning my next tropical dive video trip. (Lembeh Straights/Bunaken area in Sulawesi Indonesia)
Oh, and staying with/diving with Atlantis Resort in Puerto Galera and all their remarkable biodiversity that is all within a 10 minute boat ride to all the sights was an incredible experience-I can't wait to go back there.
Below is a frame capture from the video footage.
