Mt. Everest Photographed at the Highest Resolution

This is an amazing picture of the Khumbu glacier and Mt. Everest that someone shared with me; zoom near the area I have marked below to see the base came and also to get a sense of the grandeur.  Someone told me that David Breashears compiled this from some 400 photographs!

My collegue forwarded this link to a friend who helped spot a few climbers (see image below). There are many climbers to the left of the arrow and the top arrow is Camp 4!

If you are like me and don't know which is the summit then refer this image
Explore the entire site - there are amazing pictures.

Patch settings that I use on my GH13

After my last post on how I could sharpen my videos from GH13 I grew greedy and wanted more mega bits :) So I searched around for better patch settings and came up with the following. Until now I was using "LPowell - 100Mbps Max Latitude Native 24-25p Standard Patch v2". (By the way, great work Vitality - thanks a bunch!) Now, with my own settings I seem to get quite good videos - AVCHD videos have a maximum overall bit rate of about 120 Mbps and about 40 Mbps on an average; audio is at 192 Kbps which can be increased further. The MPEG videos are roughly around 70 Mbps and the audio is at 512 Kbps!
Here are my settings - do give it a try and let me know what you think. Especially if you have StreamParser* installed do let me know if the video is cleaner, sharper, better etc:

* To quote Vitality from one of his blog posts: StreamParser by Chris Brandin as help tool to analyse AVCHD streams -
Other good idea is also use trial version of Elecard StremEye -
