Blackwater dives and filming

01 September 2018 - 03:19 AM

Hi all,

There's a lot of fuss and hype about blackwater diving nowadays.
All topics I found are about photography. Nothing on video.
I came across few videos on YouTube:



I even found an interesting video made here in Italy:


Looking at the PBS teaser I see an interesting configuration. The guy has two Sola 4000 each in front of the other straight in front of the camera. He "simply" put the critter between the lights. Maybe with this conf he can even prefocus.

On the PBS video the guy has some light orthogonal to the lens lighting a self made piping...

So here are my questions.
Which lens and gear are best suited for blackwater filming?

Last but not the least... Has anyone ever organized a blackwater dive?
I find only tips on photograph critters. I have a boat and I would like to organize one.

Hi all,

A quick question. Do you know if the plastic magnetic circular switch is user serviceable?

Last week I dove in a river with a lot of mud and now the plastic ring is a little bit though.
I tried with compressed air, water... I guess it should be opened for a complete cleaning.

Lost In Time (Junkers Ju 52 wreck)

15 May 2018 - 02:29 AM

After two years of struggles I finally came back filming. Nothing special, just a short dive on a recently discovered wreck near Capri Island. A good chance to use for the very fisrt time my GH4. Average water visibility but pitch black so I bit the bullet and filmed everything at ISO 1250.


The Junkers Ju 52/3m (nicknamed Tante Ju ("Aunt Ju") and Iron Annie) is a German trimotor transport aircraft manufactured from 1931 to 1952. In a military role, it flew with the Luftwaffe as a troop and cargo transport and briefly as a medium bomber. The Ju 52 continued in postwar service with military and civilian air fleets well into the 1980s.
The wreck was discovered in the 2016 and lies at 72m (236ft) on a sandy bottom in the so called "Mouths of Capri", the channel between Capri Island and the mainland ( https://goo.gl/maps/QCha5zKrpa82).
Identification and cause of loss are unknown so far.
