  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Tasmania, 15 - 20 March 2012.


After many weeks of preparation and testing I was finally ready to fly to Tasmania and film with my RED Epic camera housed in the DeepX . Mike Seymour and Jimmy Shen from FXPHD in Sydney had booked their flights and were meeting me. They were coming to witness the idea that one can dip the naked lens directly into the water without a port in the quest to produce the ultimate picture sharpness underwater. A combination of curiosity and fascination had Mike confident that there would be a story to be told on this trip...

Following extensive research and testing, it is now possible to film using a submersible lens and RED epic digital cinema camera. I had been excited for many weeks about producing the first footage, right up until the day I broke my ankle and was unable to dive. Four days prior to flying out Jon Shaw from ginclearfilm agreed to fly to Tasmania to acquire footage.

Jon is an experienced underwater film maker, and was quick to accept a deep diving excursion to 37 metres with my RED Epic camera housed snugly inside the DeepX. It is Sunday18 March 2012, the water is cold and very murky off the east coast of Tasmania at this time of year and the visibility is poor (approximately 5 metres). After years of research, measurements and design, nothing was going to deter us from our mission.

Jon and the rig slowly disappeared under the water. It is difficult for me to watch and wait. I had always thought it would be me filming the first footage with DeepX. Whilst Jon is filming, I feel impatient and despite my confidence in engineering principles and knowing the design and precision that has gone into making DeepX... a flicker of doubt crosses my mind. Finally Jon surfaces after 10 minutes of decompression and says with a big grin "it's good!". He was happy with his shoot and I was relieved that science and precision engineering had not let me down. Phew!

Monday 19 March 2012, we were out on the boat again. The forces of the universe were not so kind to us and the weather conditions were treacherous. The northerly gale force winds churned the water and a strong current was pulling us south. Those who suffer from sea sickness were left behind, and testing continued. Jon disappears quickly and he descends to 37 metres, the shot line was carried away with the strong current. On his return, Jon is forced to do a blue water ascent in poor visibility to decompress for 10 minutes. Jon surfaces feeling exhausted but happy and reports that the housing handled very well and that he actually managed to take some nice images on the bottom - truly remarkable.

I would like to thank Jon Shaw for coming to Tasmania at short notice and offering his experience and help. Our trip was greatly enriched by having Mike Seymour and Jimmy Shen join us and provide assistance and contributing to the successful testing of the DeepX housing.

Wow.... incredible
 
Congratulations Pawel! So great to see images emerging from your invention.

Sorry about the fractured ankle, hope the crutches came in handy!

Thanks guys,

Yes, very happy with the images. Whilst I was confident of the results after doing countless bench testing and measurements, it is pleasing to see some real life images. What was also great to see was that DeepX is very quick and easy to set up compared to traditional housings....probably quicker and easier than setting up a terrestial rig on a tripod.
 
Who's the cubby bloke in the photos? LOL
Well done Pawel a massive effort for one person, it will be great to put it through it's paces on a slightly shallower dive where we have a little more time ;), less current and more light.
 
Thanks Pawel for a couple of fun days in Tasmania! Really happy to see the rig finally coming together and it performed so well on the first dive!
 
Hi Pawel,

That's truly fantastic, would love to learn and maybe use your technology.
Would love to use this one day on one of our natural history underwater shoots.

Can you please post a short clip / clips?
The still images really don't show me what I want to see.
The angle of coverage seems wide enough but not getting that 'Damn gotta have this' feeling.
Can you give us tech details? 4k? 5K?
Lighting is harsh and does not look good at all- but I am not looking at the cinematic part of this now.

Inventive ingenuity- well done. I would like to see more.

Thanks.


Thanks.
 
Hats off, Pawel.

Very nice to see this. Congrats on your achievement.
 
that's brilliant using the Nikonos mount directly to the epic... were you very nervous about flooding ?
I've got a parts Nikonos V on my camera shelf....

Thanks guys for tremendous feedback and support (and orders).

I believe Mike and Jimmy are working on a small clip for NAB and I'm sure they will post some motion clips soon (my computer is completely inadequate to do this). Stay tuned.

My first impression after looking at the motion pictures is the incredible and total absence of field curvature that are so characteristic of dome ports. The image is completely flat as you would expect from good rectilinear lens in the air and there is no distortions that have been haunting us since donkeys years.

On the day one we shot 5k at 60fps with shutter 1/120 mostly at f/5.6.
On the day two we shot 5k at 30fps with shutter 1/60 mostly at f/5.6 to f/8.0.

The lighting looks harsh mainly because of poor visibility and positioning of the lights. We had 24,000 lumens down there and it is very hard to make this not fall off very quickly when mounted on the rig. Also my grade in RedCine didn't help :)

Jon, You are welcome any time. We can go filming the sea dragons in 15m water next time. I was impressed how well you handled this difficult dive. I wanted to put the camera through the paces and I can't imagine more difficult and challenging conditions.

Thanks Matt,

Nervous? Not really. The Nikonos lenses are pretty reliable and the bore seal around the lens is very precise and well engineered. The production unit also has channels routing potential leaks to the bottom of the housing and away from the camera. We also have the ability to pressure test the housing using two LP ports on the front of the housing, which we did. It is quite simple and reliable setup.

The only active o-rings are in the titanium on/off Recod and User switches and, as we found out in a dry test, it is so precise fit that it seals even without any o-rings installed! (And normally it has two redundant o-rings). This housing sets new standards in precision engineering.

I've got a parts Nikonos V on my camera shelf....

Looks like your parts may need a companion to put them into a good use again :)
