    Blurry snap of an 11x14 carbon transfer. On pearlescent acrylic sized Canson Montval. Kodak Ortho Green xray film. Impressive stuff, sharp as a tack and contrast to burn, printed this with 4,5% AD on my lower contrast tissue. Thanks Stephen, Michael, and Rudy at ecbuyonline. I really like this size, once you take off a strip on the long edges for the holder tabs its very close to 10x14/5x7 aspect ratio. Fits perfectly on an A3 sheet of watercolour paper.

    No, both sides. Its not Delta 100, but seems ok. There is a data sheet for it somewhere in the xray thread that sayes its tgrain emulsion. It does scratch easily but its not that bad, the main problem for me is finger marks and density on the edges. And too much mush from using f22. 25 sheets of 11x14 FP4 costs USD250, 300 sheets of xray cost USD210. a 5x7 print is easy, nearly every negative is sharp and printable but 11x14 is a bit more of a challenge.

    Re: post alternative techniques

    And since we are at it - here is a real "alternative" technique for you. A "Winther direct positive" - between friends also called the bichro-silver.

    This is a process published in Norway in 1845 by the author, publisher, printer Hans Thøger Winther (1786-1851). It is based on the sensitivity of both bichromates, and silver chloride. A bichromate-coated sheet of paper is exposed in camera, and produces a negative image with the highlights made of "cooked" bichro. The paper is then salted and sensitized in silver nitrate, and then exposed to direct sunlight: the silver will darken where the bichro has not hardened, thus inverting the image and producing a direct, in-camera positive. It's all still very experimental, and a very finicky process…

    Interesting. I bet that would work with carbon tissue too, if it was used in place of the silver and it could be eposed from the back through a transparent base.
