One thing that is of great interest to me are early colour photographs from the turn of the century.

Along with a method using normal B&W images using a 3 coloured plate technique   there were two others used at the time. The Autochrome system (developed by film pioneers the Lumiere Brothers) and the Paget Plate system.

Autochrome:
was a single piece of glass comprising both the colour screen and the photographic emulsion, or coating. The colour screen was made up of dyed potato starch grains that had been separated to a uniform size, dyed red-orange, green and blue-violet, and thoroughly mixed together. The mixture was applied to a varnished glass plate while the varnish was still tacky. The excess mixture was brushed off and the plate passed between steel rollers to flatten the grains, resulting in tiny colour filters between 0.006 and 0.025 millimetres across. Any space between the filter elements was filled with carbon powder. The plate was then varnished, and when dried, a standard black-and-white emulsion was overlaid. The plate was exposed in reverse; that is, with the glass side of the plate to the lens so that light entering the camera passed first through the colour filters before exposing the negative. The exposed plate would then be processed in reverse, so that the image produced was a positive. When viewed with a light source behind it, a colour image was displayed.

Paget Plate:
The Paget system was a development of the classic colour screen plate system using two glass plates, one of which was the colour screen while the other was a standard black-and-white negative. The Paget colour screen plate comprised a series of red, green and blue filters, laid down in a regular pattern of lines to form a réseau, or matrix. One of the claimed advantages of the Paget system was the use of separate “taking” and “viewing” screen plates. Because the negatives of the time were so “slow”, the colours in the taking screen plate were diluted, which let more light through to the negative, resulting in a quicker exposure. The viewing screen with more intense colour was used in combination with the positive image.
The sale of Paget colour plates enjoyed moderate success up to 1914. In 1920 this plate was renamed Duplex and continued to be sold for a few more years.


Here are a couple of links to show just how amazing the early photo's were, inlcudes photo's from pre-revolution Russia, WWI and more.

http://www.poiemadesign.com/wwi/ - WWI images
http://www.brightimages.co.uk/grandma/ - some personal shots from 1916

And I bet you didn't know that Frank Hurley took colour photo's during Shackletons ill fated Antarctic expedition of 1914-16- some in this collection - http://www.spri.cam....ndurance/1.html

There are others if you search but these are rare early images using glass plates that were all too easily broken.

Not sure if any of you have seen this.

But last year in May Eurocopter set a new altitude record for a single engined helicopter, although getting up to 33,500 ft on test flights something more spectacular was planned, a trip to only 26,000ft.........however this flight would take place in the Himilaya mountains and one particular object is about 26,000ft tall. The helicopter would be taken up to the summit of Everest a feat never before achieved or even attempted due to the fast changing weather conditions and freakish updrafts at the summit. Not only this but the helicopter would land on the very summit, although not flat enough for a proper landing all that was required were for both skids to be in contact with the summit for at least 2 minutes..............so the attempt was made

Here are details plus videos, one highlights video embedded.
