Yes. About half way up the face, just to the right of all the avalanche paths.

Yep it is. It is on Lhotse face. Zoom in between the V shaped valley you can see people crawling up to Camp 3.

It can be taken using any camera and any telephoto lens. You need to take multiple photos at high zoom (mag factor) typically using a motorised head (like Gigapan or Celestron Skywatcher Allview) to scan the landscape and take the shots and then stitch them using software.

A good article by Microsoft Research explaining the process - http://www.cs.princeton.edu/courses/arc ... apixel.pdf

Effectively you need the following:
1. Good camera with Telephoto lens
2. Panning head (preferably automated ones)
- Giga pan (http://gigapan.com/cms/shop/epic-pro)
- Celestron Skywatcher Allview, I just purchased this (http://www.celestron.com/astronomy/cele ... mount.html)
- This talks about how to build your own (http://brewzone.com/2008/11/10/diy-pano-head/)

3. Open source software (or potentially a hardware controller) to drive the head
- Open source Papywizard (http://www.papywizard.org/)

4. Stitching software (any of these)
- PTGUI, I use this (http://www.ptgui.com/)
- Microsoft ICE, free but limited controls (http://research.microsoft.com/en-us/um/ ... s/ivm/ice/)
- Hugin, Open source but tedious to use (http://hugin.sourceforge.net/)
- AutoPano Giga (http://www.kolor.com/image-stitching-so ... -giga.html)

5. Host tool/software and sites
- 360cities.com
- Krpano.com
- Microsoft HDview creator to host on your own site, needs an activeX plugin on the browser (http://research.microsoft.com/en-us/um/ ... vm/HDView/)

I just started playing with the above and it is really interesting!

Even with the tools it is not easy to take a photo like this

1. Firstly lugging up all the equipment (I would imagine) would have been painful
2. Weather conditions, hence the light conditions, change very quickly so will need to complete the process quickly to ensure that the final stitched image doesnt have different lighting and appear seamless (typically stitching software help with this)
3. If dynamic objects are involved, like people or fast moving clouds, then will require manual intervention to align/mask out objects - can be laborious
4. Requires few hundred (possibly in the thousands) photos to be stitched, so requires lot of CPU time

This guy has done a wonderful job!

Very cool photo.

Just another reminder that if I want to hang out with a bunch of people, I can just drive into town. I'm sure their population in climbing season is similar to the town I live in.

If you say so. Trust me on this. The people in EBC are nothing like the people in any town you can drive to.

Well I'm glad someone finally said it. Everyone is hating on this place yet none one of the haters has ever even been there. I'm sure it is an interesting experience. Probably beats what most folks here have done in the last month.

It isn't a rock or anything... there is nothing else like it. A warming up for hot tea and cocoa, maybe play some cards, before continueing up?

Also the prayer flag. Initially noticed the lower one, and now see there are several more. At first I thought this was camp one, but I think camp one is out of view on the right just as the ice fall ends. Looks like these flags are just positioned for good karma on a particularly exposed to avalanche portion of the route. There is fresh debris within the photo. Also note the group of three in the top right.

I'm pretty sure that thing up there in the snow is a yeti. I heard they got a bunch ubm up there.

Ignorance showing here, okay? But which mountain is Everest? sm176811 said there were climbers on the Lhotse face, which I found, so does that mean Everest is to the left of the V-shape?

It seems every time I study this photo, I find new things. What a great Christmas gift to us!

This should provide you a map of the route.

Yeah and if anyone is worried about crowds, just pop around the back to the Kangshung face. Should be fairly quiet there.

I was referring to the amount of people, not the type of people.

Also Chad, just last week I completed my undergrad work. Took over 4 years and around $45,000. Now its done, and I can move on in life, I wouldn't trade that for visiting EBC. So in my case and my opinion, visiting EBC does not beat what I have done in the past month.

Well, it's simply a matter of priorities and where you want to go with your life. I certainly don't claim to be a role model.

The photgrapher of this photo, spent a winter living in a cardboard box in Jackson WY. Wanted to learn how to climb that bad. I'm sure he doesn't claim to be a role model either. He carried an IMAX camera up Everest.
