  • 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 :)

DEEP ATOM down under

Having at last seen the finished unit of the GATES DEEP ATOM, I must say that it did made me fill sorry not to be allowed to Dive, but give me some time, and not all bets might be off... JUST YET... ;)


With John at NAB...

Well guys....

finnally got around to writing the article on the flat port test wide lens test....that was mentioned in the first few pages of this thread.

or go straight to the article on my blog here....

Enjoy!

This is very relevant as since I will be getting training at Gates for the DeepAtom pretty soon and will also be testing another underwater beamsplitter housing/rig in the near future.

enjoy have fun and let the comments flow...... (maybe we should discuss my test on my thread so as not to hijack this one?)
 
Pedro, thanks very much for your work and making it available.

Ill post back here with our results using a side by side twin dome rig as soon as test are complete which may or may not result in a usable system. Unfortunately we are not using Epic for this application as 100mm or more IA is not usable for our needs underwater in a side by side configuration. Currently we are able to work down to 42mm IA with 2/3 camera heads.

Id also add Im extremely impressed by Gates Deep Atom rig. One day Id hope to own one.
 
One again I empasize....my tests are primarily geared towards Feature film applications.....like the ones you would be using a "Deep Atom" for.

I'm sure you will have good results on your "Double bubble" housing

I'm not debating the physics involved just presenting results and letting people choose what they want to do. After all as you point out we don't have a choice with a beamsplitter.

I will be working with a Pablo artist to "correct" one of the distorted 14mm or 16mm charts ....just to show an example of what you would do with a distored flat port shot on a big budget feature.

Once again, lets move the discussion of my test to my thread. Keep this thread focus on the original topic.
 
Pedro, again my congratulations on the test. I found it very well written and informative.
.
 
I am pleased to report that I am halfway through my DeeP Atom training and orientation course at the Gates facility not far from San Diego. The course has been organized by Bob Cranston a legend in underwater 3D film making who is representing the amazing team at Gates Underwater Products. I will have the pleasure of configuring my own Deep Atom system precisely the way I require it for my own productions at the Gates factory which will ship my housing and follow me back to Australia at the same time I leave the USA. Bob Cranston is a master of this technology and has been extremely detailed and thorough in passing on the knowledge of this extraordinary underwater 3D system. I congratulate John Ellerbrock and his wonderful team at Gates and I am excited to return Down under to begin my own 3D journey into this brave new world. Robert Settlemire and Willem Lundy also contributed to the success of this course sharing their wealth of experience in the stereo world. Thanks John Ellerbrock for making this dream come true :-)

After a 2 year journey with everyone at Gates Underwater Products and associated companies, I am finally finished my Deep Atom training. My Deep Atom unit will ship this week to meet me back in Australia. Here are some images of the training session in Southern California with Bob Cranston master underwater cinematographer teaching the course. Group photo shows left to right John Ellerbrock, Robert Settlemire, Bob Cranston, Willem Lundy and me thoroughly pleased with ourselves at the end of pool training.

Congrats Ross....Bob is the Maestro! Best to you shooting out your way....by the way, trim looks excellent...is it as good as it looks from the pics?
Well done Gates!

Thanks Johnny
yes Bob is amazing and the trim is perfect. Infinite ways to distribute weight around the housing with the new spin on brass weights. It is perfect balance underwater for such a big rig.
 
congratulations, Ross.

How difficult it is to control/prevent internal reflections off the mirror?
What's the total weight of the rig?
Can you show how to control convergence and other alignment features?
I presume that it is the first or only in the world, not just Australia? Am I correct?

I'm sure I will have more questions. Look forward to a thorough review and some images.
 
Looks great Ross, much more manageable in the water than I would have originally thought. Do you have both monitors in the housing side by side?
 
We are using the Transvideo 12" anaglyph monitor and Deep Atom is extremely manageable in the water. We actually tried to create internal reflection in the training pool but I could not notice any using both top light source from the sun and artificial light sources on and round the bottom of th pool....no reflection. This is one extraordinary machine!
 
How do you find the anaglyph monitor in deep/blue water with blue channel being much stronger than red? Particularily for the background subject? Are you able to isolate Right and Left images with Red and Blue? Or, do you use other separation channels?

I was considering the 9" anaglyph Marshal monitor, but decided on the auto-stereoscopic (glasses free) MARSHALL OR-70-3D Orchid 3D because of the above concerns.
 
The marshal is better because of the "Difference mode" but the transvideo is superbright at 1300nits. I'd rather side with the brightness. All I need to do is judge my parallax values and the anaglyph mode works well enough for that.

The spin on brass weights seam like the best idea I have seen for trimming these rigs! very cool!
 
John:

It's not easy to impress another housing manufacturer, but I have an idea of what it took to produce and that is one beautiful rig.

Ross:

It looks like you have one of the first , if not THE first, practical, fully capable, U/W 3D rigs. I have been toying with some low rent 3D U/W rigs for a couple years, so I Look forward to seeing some great things from your rig.
 
Thanks Michael it's been an interesting journey I can't wait to get this puppy in the ocean on the Great barrier reef.
 
Ross,

As the little guy looking up on a formidable mountain of achievement, please let me extend my congrats to you. John E has produced a magic piece of equipment, now it's up to you to run amok with it, show us all what is possible. Could not think of a better venue, Port Douglas, and all the Great Barrier Reef out there, words fail me. Green with envy.

Looking forward to your stuff mate, all the best.

Tom

Thank you Michael. Coming from you -- an established reputable brand -- your kind words have gravitas. I'll pass them onto the entire team.
