Regarding Tom Cochranes Blu-ray Disks and RAW footage.

RED CineX pro and RED player are free downloads from the company. Seem to be full versions not trials and no need for a registration key.

My copies seems to be working.

In case anyone was wondering about the helo traffic over Mammoth last night and this morning....there were two other SAR incidents....a fallen climber on Clyde Minaret, and an injured person at Marie Lakes.

Clouding up very heavily up here today.....looks like rain here soon.

I'm not going to comment anymore on this

And you shouldn't.

I've had university course work in Aerial photogrammetry and remote sensing and worked in environmental consulting for 5 years looking at 9" x 9" 80% overlapping high resolution b&w aerials for surveying work day after day after day.

It can be done with one camera, sequential shots, separated by large distances. The greater the horizontal distance between sequential images the greater the parallax effect. Which can be a hyper effect but very, very useful.

It isn't hard to do and we've been doing it since the time photography was invented and we could get up in the air above the landscape ...

Longer base line for distant objects "Hyper Stereo"
"For making stereo images featuring only a distant object (e.g., a mountain with foothills), the camera positions can be separated by a larger distance (called the "interaxial" or stereo base, often mistakenly called "interocular") than the adult human norm of 6265mm. This will effectively render the captured image as though it was seen by a giant, and thus will enhance the depth perception of these distant objects, and reduce the apparent scale of the scene proportionately.[32] However, in this case care must be taken not to bring objects in the close foreground too close to the viewer, as they will show excessive parallax and can complicate stereo window adjustment.
There are two main ways to accomplish this. One is to use two cameras separated by the required distance, the other is to shift a single camera the required distance between shots.
The shift method has been used with cameras such as the Stereo Realist to take hypers, either by taking two pairs and selecting the best frames, or by alternately capping each lens and recocking the shutter.[28][33]
It is also possible to take hyperstereo pictures using an ordinary single lens camera aiming out an airplane. One must be careful, however, about movement of clouds between shots.[34]
It has even been suggested that a version of hyperstereo could be used to help pilots fly planes.[35]
In such situations, where an ortho stereo viewing method is used, a common rule of thumb is the 1:30 rule.[36] This means that the baseline will be equal to 1/30 of the distance to the nearest object included in the photograph.
The results of hyperstereo can be quite impressive,[37][38][39] and examples of hyperstereo can be found in vintage views.[40]
This technique can be applied to 3D imaging of the Moon: one picture is taken at moonrise, the other at moonset, as the face of the Moon is centered towards the center of the Earth and the diurnal rotation carries the photographer around the perimeter, though the results are rather poor,[41] and much better results can be obtained using alternative techniques.[41]
This is why high quality published stereos of the moon are done using libration,[42][43] [44][45] the slight "wobbling" of the moon on its axis relative to the earth.[46] Similar techniques were used late in the 19th century to take stereo views of Mars and other astronomical subjects.[46]


3D from aerial photography video can be a great application for searching for lost people that might be exposed in the aerial imagery ...

Norman Clyde succeeded in finding Walter Starr Jr by:
Thinking out what equipment Starr had with him;
Working from his last known location (camp at Upper Iceberg Lake, I believe now known as Cecile Lake);
Knowing he had climbed Michael Minaret previously on the trip (summit register and photograph)
Exhaustively pursuing all likely routes;
Re-searching routes that Eichorn/Dawson et. al had already searched;
Looking very closely around him;

Known facts:
We know what Matt had with him. Principally ice axe, crampons, no significant camping gear.
The last peak he climbed was Clyde Minaret just prior to his last excursion.
He would have been well aware of the local snow and ice conditions at that time (Clyde has a 360 degree view).
Tom Cochrane's photos show very little ice and snow in the range right now.

Given these facts, I would presume he was deliberately bound for an objective requiring firm snow/ice travel at least on the approach or descent.
This should narrow the search area of most probable success to the regions above, on and beneath the snow/ice in Tom's photos.
Also any likely bivvy sites, primarily the lake shores.
There may be something to gain by re-searching previously searched locations with a different pair of eyes.
Matt COULD be anywhere out there.

Searching moats/bergschrunds should not be taken lightly. They are highly unpredictable and can be very difficult to escape even with assistance.
(a climber died in the Tetons in mid-July after falling into a moat at an opening in a snowfield. He was seen by a nearby guide (with radio), was retrieved alive in less than an hour, helo'ed to a hospital and still failed to revive).
Be careful out there.

your photo with the orange blob.
Is that a true color image or enhanced? Or false color from a converted IR image?

HighTraverse, et al....

As I said in my TR, it is important to NOT get myopic in this search. Yes, from the evidence of missing gear and the conversations, Matt was heading for snow and ice. However, enroute to those things, there are literally thousands of places he could have met with problems.

The reality is....the amount of time that as lapsed between July 17 and now is huge. What remains is tiny......and scattered.......and God knows where.

Searching bergschrunds should not happen. One must ALWAYS weigh the risk vs. benefit criteria.

we did minor color, ASA and exposure corrections only to improve resolution...pretty close to true (human eye perception) color

as Cragman points out, there are lots of rocks in that area with that color

it is an odd chance that this color is similar to Matt Greene's tent...which he did not carry with him...and his rain fly is grey...

the RED camera is rather sensitive to IR, which is why we use an IR filter, to prevent washing out the human sensitive color spectrum

i haven't looked into using this IR sensitivity to detect warm bodies i.e. using a visible light filter that passes only the IR...i don't have one of these in my big collection of Hoya or Tiffin filters

Aug 19, 2013 - 12:28am PT
Tom, the IR sensitivity in a typical digital camera detector, like a CCD or CMOS, would not be good for detecting people or animals. Its sensitivity probably only goes out to about 1 micron or less. You would need a thermal IR camera (~10 microns) to detect heat from a person. Thermal IR cameras exist, but the detector technology is different and typically much lower pixel count than cameras designed for the optical.

This may not be much help, but just in case, I climbed Amelia Earhart Peak from Lyell Canyon on Aug. 16. No sign of Matt on east or west sides of Potter Point, nor in the register.

I've looked at the videos--he does look a lot like the person I've seen in Luther Pass/Big Meadow... but then, again, there can be a lot of people who look alike. I've seen that person wearing ball cap/hat mostly, and only once without a hat--he had receding hairline, so very high forehead, and his height appeared to be about 5'10-5'11ish.. The video doesn't show a lot, of course, and the helmet is on.

I didn't notice many details--whatever I noticed back then I forgot by now, like the tent and the car, if there was one (backpackers like to stay in this camp sometimes, it's a primitive camp near Tahoe Rim trail). That person was in site #1 or 2 (these are back to back sites), and the tents in one of these sites tend to be way back where you can't see them. No facial hair. Sites #1 and 2 share one parking spot there, so you can't tell whose cars are parked, actually.

Ok something is bothering me. Tioga - did you see this picture of Matt?
Check the hairline (a little bit of "recession") - just wanted to revisit this because it was sort of nagging at the back of my mind.

Like I said, the guy in pictures and videos looks A LOT like the person in Luther Pass camp; he was traveling alone and yes, his hairline looks the same (I saw him without a hat only once, other times in a hat). But there're a lot of people who're look alike in the world...and there was no reason for Matthew Greene to be in Luther Pass during the second half of July. So, in all likelihood, just a look-alike. Also, that guy was pale, not tan. He didn't seem to be in distress and was well-groomed, wearing dark-colored clothes. Seemed to be friendly and really curious about surroundings, staring around a lot instead of staring ahead like most do when walking. There's no just explanation for M. Greene being there, at that time.
