  • 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 :)

Interesting information...

Red seems to undertake nothing EXCEPT daunting tasks. If you REALLY wanted to make a dedicated sliding sensor, you guys could accomplish it.

Just using a single large sensor makes more sense. And designing a high speed/precision motor that could handle the sliding mechanism would most likely be as expensive as simply using the bigger sensor.
 
It's been done on film a long time ago. Remeber Stereovision? They were the folks who brought you "The Stewedreses" I believe still to this day the only soft core porn film ever released in 3D. It grossed over $100,000,000. Any how it used divirging prisms infront of a single lens housing that had two imaging lenses that put two seperate images on each frame of film.

Two or three lenses on the 617 will be fun and practical. However there are many times when a base separation between left and right lenses either needs to be smaller than placing two lenses side by side, and some times it needs to be much larger I.e. of the order of meters (some times hundreds of meters e.g. 3d recording of clouds, mountains etc.). I think convergent camera arrangements will become less and less common in favor of strict parallel arrangement. Stereo cinematographers will also(learn how to shoot with wider base separations without adverse viewing effects.

Synthetically made up stereo I.e a new stereogram from a mono only image really does a disservice to what true stereo is really capable of.

For many years we have been taking very high res high quality stereograms of historic architecture (for preservation recording purposes); and with good photography and the right set up you can pick up an amazing amount of rich and beautiful 3d detail that not even LASER scanning can provide. In the software we have developed we can combine this rich 3d stereo detail directly into explicitly modeled 3d models extracted from the stereogram itself (yes we do have patents for this process). With some of the processes it allows you to shoot with wide base separations to capture fine and rich 3d detail, and then resample the parallax so that you have very rich 3d but in a very comfortable viewing range of parallax. We are very exited about being able to apply our technologies to stereo cinematic applications, and are hoping that cinematographers will learn how to take really good stereograms that are rich and engaging. Synthetic stereograms from mono cannot do this convincingly and frankly are very poor substitutes compared to the real thing, especially for complex real life subjects.

Real stereograms are the only way to go if you want to be real and look real.


[Just to add, one of things about RED and REDONEs that stereo cinematographers really appreciate is STABILITY of the sensor over film. The natural jitter in the film gate causes stereo sequences with mal aligned stereo pairs that also jitter and breath (not good for feature length stereo presentations). A stable high resolution digital image is far superior to film for stereo applications as it is possible to have near perfect alignment and total stability. The stereo “eye” is very sensitive to very small parallax shifts of the order of a ¼ of pixel. The idea of dynamically shifting a sensor to shuttle back and forth to serve two lenses is theoretically possible but for practical purposes represents a step backwards perhaps in technology. However some of the most unlikely technological ideas such as DLP have made it through and have been very successful.]

We've missed you for all the Red NABs, sir. :devil:

Really, I want to pick your brain about exhaust headers for Dodge 8 cylinders and aluminum swage techniques.

Hmmmm...

Do I know you? I am a bit fimiliar with Mopar products and have swaged before in my life. lol

Stay away from aluminum and stainless headers they don't expand or contract at the same rate as the cast iron block does. (think lens mount) lol They will either warp or leak on you.

Dilavar or Raceware engine studs are essential upgrades on pre 1984 Porsche 911 motors. ( After '84 they were standard ) The steel ones don't expand enough and tear out of the engine casing when the cast aluminum engine get hot. Not sure if that white 959 goes out for a proper romp very often but that's what's holding the cylinders in place when it does.

Alfa Romeo used in the 60ies and 70ies aluminium headers on cast iron blocks. This classic beauty of a 4 cylinder engine reached quite a milage when used properly. To warm up the engine 3000 RPM were the sweet spot. After 10 minutes the engine was ready to run. And they ran.

My '71 has a cast magnesium engine casing. The engine never let me down in the last 10 years and 50.000 miles and is still taken out on a proper romp. Sensitive warming up is madatory though.

Hans
 
Yeah but people who drive big block 440's, 383's, hemis etc. are not real well know for gently warming up their engines. lol

My Super Bee with it's pair of 750 double pumpers would have probally melted an aluminum exhaust header.

You've been dropping too many hints over the past couple years on here about your MOPAR knowledge to ignore, dude. I'm just guessing that your OCD for cine products extends to other subjects. :shifty:

Good god no! I am thinking of ruining a 440 in a 1985 Dodge Power Wagon by trying to get it to run on a wood pellet gasifier. The swaging would come into play for the ducting to get the gases to the intake. Some kind of aftermarket header might improve things as well.

Sony has a demonstrator of their SLR in some stores that shows how the chip moves for image stabilizing, not nearly the travel distance that you would need for 3D (it moves about half an inch in x and y directions) but it is incredibily fast and precise - pretty phenomenal and fascinating to watch.

The other problem as I understand 3d is that with two lenses you really need to vary the distance between them for proper 3d, which would require some sort of moving lenses and then the chip would have to know the distance and adjust. Difficult but probably not completely unfeasible (is that a word?). The Sony demonstrates moving the sensor with the necessary speed and precision and even though you would have a longer distance to travel it could be on a straight track so it would just be back and forth.

On the other hand, I don't know how much more electronics and wires you have to have on the RED sensors over the sony slr.

PS Sorry to interrupt the car talk LOL:biggrin:

Morning..

What's OCD? I thought I had the last of the power wagons in a '79 model (short bed stepside), After that wern't they called Ram?

Hi Matt,

I had a lot of issues with a 2.7 911, but never had any issues with either the 3.0 SC 180 (1979) & 204ps (1983) engines.

OCD is an acronym for Obsessive Cumpulsive Disorder. I would imagine everyone looking at this sight on a regular basis is afflicted.

And yeah, those late 70s jobbers became the RAM in 1981. I think they drug out the Power Wagon designation for those Macho edition ones.

I have just had this on the brain recently which is why I said Power Wagon:
