  • 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 :)

Once I learned that Pictorvision was developing 3D version of the gyrostabilized Eclipse gimbal,
I wanted to be the first to try it, so we scheduled a 1-day helo shoot in LA.
We were fortunate to get Ken Corben to be our stereographer. :)
For those of you interested in the story, I’ll share how the process went below:

The Crew:

Ken Corben -Stereographer
Renee Treyball -Ken’s first AC
Jacek Zakowicz (OptiTek) -Collimation
Jake Capistron -Pictorvision tech
Phil Bates -Director
Annette Gaillard -Phil’s AC
Diane Barrows -Production assistant
Doug Holgate -Camera operator/DP
John Tamburro -Pilot


The Goal:

To capture a variety of subjects that would maximize 3D depth, and work for stock footage.
Since our I/O would be 6.5”, this would mean a lot of low level work.


Even though the shoot was scheduled for 1 day, the prep took 2 days and the rigging took another day.
We brought our two MX Reds and rented 4 RED RAMs plus 2 Optimo 17-80 lenses.

After arriving at the Pictorvision shop, we installed the Reds on the “Eclipse sled”. Ken gave initial
camera settings to Annette and we got to work.

Jacek uses his Optimator to check collimation, and we ended up adjusting one of the lenses to match the Red sensor.
In this photo Ken is on the left, Jacek on the right.

After installing the hardware, Jake balanced the cameras on the Eclipse, adding weight to the back because the lenses were so heavy.

We remove the camera sled and position the cameras to point outside to get distant views.
Renee works together with Jeff to program the Preston HU3. The purpose is for both left and
right to match zoom, focus and iris in all the incremental points throughout the range.

The Preston HU3 in the foreground. It feels great in the hand, incredibly smooth and precise.
The camera operator will need to operate both this and the Eclipse control desk.
(edit: I've just heard that Pictorvision has since incorporated these controls into the console)

Jake tweaks the system. He is holding a blank “cover” from which he will cut out the camera viewing port.
The final cover is shown in the inset.

On “rig” day, we move everything to a hangar at Whiteman airport. Jake installs the support hardware on the A-Star.

Phil, Doug, Jake and Ken transfer the 200lb Eclipse to the helo.

Annette helps Jake re-install the camera sled.

After final balance adjustments, ND9 filters are installed, Annette helps Renee with final HU3 programming tweaks while
I look on.

The prep and rigging has gone well with no major hiccups. So, finally we're ready for a test flight.
Jake, Ken, Renee and Jacek have been great to work with!

Before lift off, we get a photo with (left to right) Tom Hallman (Pictorvision President), Phil Bates,
Doug Holgate, Jake Capistron and John Tamburro (taking the pic).

After a short flight which includes a close pass of some trees(a frame is included below) and radar towers, we copy some shots
to view on my laptop. The left and right images match with very little geometry adjustments needed. We declare the rig ready for shooting!

That evening we take off to shoot close ups of downtown LA.

The next morning we take off for downtown LA again and get some great low level clouds along the
way. We then took off west to the industrial areas around San Pedro. We land at Long Beach which
becomes our base of operations. We then head West to Catalina and get some great coastal rocks,
birds and surf. Because of flight restrictions around LA we need to find remote places where we can
get close to our subjects.

We made the most of the time and opportunities we saw, shooting as much footage as possible. After
each sortie we swap drives and get back in the air. With only 2 pair of RED RAMs, Annette and Diane
quickly copy the files to portable hard drives we brought along. They easily kept up with us, so we
always had fresh drives waiting. (And yes, we made redundant copies). :)

Over the next several weeks, I process the footage with a special template I created in AE and am
pleasantly suprised at the beautiful depth of these shots.

Still there were some lessons learned. For example, while shooting I am looking at a monitor showing the right view,
and Doug is monitoring the left view. I am trying to avoid flares, and on some shots where I thought we were clear,
the left cam had a flare I couldn't see.

I would also consider a little less field of view, (push the cameras further back into the gimbal) to avoid flares better.
For me it would have been a good tradeoff.

I’ve always loved shooting aerials and being the first to use this gyrostabilized 3D rig was like a
dream come true. My sincere thanks to Pictorvision and the first class crew we had working on this project!

Even though I lack the 3D knowledge and expertise of most on this forum (which may be obvious the
more I write), I hope you find this thread interesting and perhaps helpful.

I’ll make a separate post to show some anaglyph frames.

Phil,

Sounds like an excellent adventure, congratulations! the 2D versions of the clips look great, the anaglyph ones are not loading for me? There's a bit of cardboarding effect of the frames you posted, perhaps suffering from the same extreme positive parallax as your frame exposing the problems with AVCHD compression...I could never work with the footage you sent me, being not in HD sizes, none of my softwares were able to convert it for stereo convergence, these apps are somewhat restrictive. Pity I could not help, but it looks like you have very impressive footage, and especially so once you manage to tweak your settings to separate the depth planes. Good job, you're having fun!
 
Hi Rudi,

Thanks for the feedback. :) I'll check in to the anaglyph issue. Regarding the need for HD sizes, we do have free HD watermarked versions. If you go to this particular clip...

http://www.artbeats.com/clips/004-C035/S3D-HD

...then look on the right side of the page you will see a link called "download comp options". This will give you access to the HD watermarked versions. This clip has only 1% positive parallax as do most of the aerials.

Considering some of the things you said, I wonder what you think of our "S3D Guide". If you have time to view it, any feedback positive or negative would be helpful: ttp://www.artbeats.com/demo_reels/37

Thanks,
Phil
 
Phil,

The anaglyphs load, they just appear as unresponsive but then show up all of a sudden, so I could view the clips. Both the S3D Guide and the 3D Demo are superb. The guide might feel redundant for people who already know all these technicalities but even then I appreciate its thoroughness and effort to simplify/improve the use of your website. Beginners would appreciate it even more. Your clips look good, there's an obvious effort to photograph in a way that places foreground and background images at visible separations and thus create good 3D. I'm still getting that uncomfortable cardboarding feeling from some of the clips, not all to be fair, but of course I'm sure that were I buy this footage, I would be able to adjust parallax values at will on my own. Did you keep the 6" IO constant for all the aerials or did it change? I'm sure you know but as you zoom in, especially any time you go past 30 mm focal length, it is important to increase the IO to avoid cardboarding. Images look great though, I will download a few comps, converge them myself and see if I manage to eliminate some of that flatness.
 
Thanks again Rudi, for the feedback. The 6" IO stayed constant on the aerials. However, in some rare cases (where the cam was pointed perpendicular to the direction of travel) taking the R and L streams out of sync one frame can increase the IO to 3 ft. The cloud and LA downtown anaglyph images above use that method.

I certainly understand the cardboarding problem. I think it's just our inexperience showing through at this point, we will be improving as we go along. :)

Thanks for sharing.
It amazing that everything you guys did is to some degree pioneering.
I am jealous:)

What's the focal length in arial shots that "worked the best" ?

The lens went to 17mm, but we risked vignetting wider than 19mm due to the right edge of the port hole. It turned out that between 19mm and the low 20s worked the best for us.
 
thanks Phil, footage looks great.
Perhaps it's obvious, but don't have much experience in 3d.
In case of flaring on only one lens, is it districting when combined in stereograph image?

Yeah, it doesn't seem to work. Even if there are flares on both sides, it doesn't seem to work, -at least for me.

By the way, I don't have much experience either, just been cramming the last 6 months. I just know we need to go there, so we're diving in with both feet. :)

Phil,

Very nice work, thanks for sharing, lot of useful information.
We are doing some high altitude 3D aerials at the moment hope share more info soon.

Great shoots thanks for posting Phil!
I'm glad the Red Ram worked out for you!

Ketch, I'm with you on Anaglyph. It's not something we sell, I just used it because it's the most convenient (and universal) way to post something the whole forum can see.

Thanks for the feedback!
