  1. For you blackwater divers (and everyone else to be sure...) here's a fascinating article from The Smithsonian about aquatic animals and their daily vertical migration: https://www.smithsonianmag.com/science-nature/what-drives-aquatic-animals-to-make-vertical-migrations-180979172/?utm_source=smithsoniandaily&utm_medium=email&utm_campaign=20211207-daily&spMailingID=46066346&spUserID=NzE1OTY3OTQ2MTczS0&spJobID=2140798550&spReportId=MjE0MDc5ODU1MAS2

    Enjoy,

  2. Tropo,

    People who’ve been vaccinated have been infected

    Not sure what you meant. The vaccines develop antibodies in the persons who have had the shot(s), but having the shot(s) does not imply they have been infected. Think about it: if you get a flu shot, it does not give you the flu! You develop antibodies as a result of the shot.

    Persons who have had the vaccine can still possibly transmit the virus without being infected, which is why the current advice is to continue with mask and social distancing. There are studies ongoing to confirm or reject this idea, so until those are complete the precautions are quite logical.

  3. Interesting claim about processing power needed on the 12K camera's page at BlackMagic:

    As an incredibly efficient next generation codec Blackmagic RAW lets you shoot 12K and edit on a laptop, a capability that simply isn’t possible with other codecs.

    Obviously I have not tried it (grin)...


  4. Int,

    I use a Sony AX700 and recently experienced a huge improvement in autofocus success underwater. A diver heard me complaining about focus failure using WIDE, and suggested I try CENTER focus. Oh, what a complete difference it has made!

    Here's a bit of detail:

    Including CENTER, there are five focus modes available for the AX700 camera in video mode. The other four are MANUAL, ZONE, FLEXIBLE SPOT and WIDE.

    ZONE and FLEXIBLE SPOT are available if the screen can be touched or if the joystick can be operated to indicate to the camera where to focus underwater. These aren't available on the Gates housing.

    So until recently I used WIDE, following the recommendation of the "experts." This resulted, as you mentioned, in lots of focus hunting and failures to focus. Very frustrating.

    When I switched to CENTER focus, magic seemed to happen! Most of the out of focus moments went away - my footage is in focus probably well over 90% of the time. What a great relief!

    Hope this helps,

    Tom

  5. Not sure if anyone else has an external ear problem. If so, I used to have it around once a year,  and now I use Doc's Pro Plugs. No problems since we started using them about 5 years ago. I have no interest in their company - just a customer who thinks they work for me.
