we should wonder if “the structure of the TS fibers itself and/or the presence
of a thin layer of impurities at the surface of the whole fabric
play a crucial role in the image forming process.”
Thibault Heimburger has put together an extraordinary collection of Mark Evans photomicrographs (from 1978) to which he has added some comments. I had hoped to simply display all of the pictures here along with the captions. So far, I haven’t succeeded. These are large scale images contained in a single PDF file and I have not been able to extract some of them from the file. Nonetheless, I can provide you with the PDF file and you can view the images that way.
You should note the following from the first page of the PDF:
MARK EVANS ‘ 1978 PHOTOMICROGRAPHS
©Thibault Heimburger- November 2013 (for the captions and comments).
All the pictures are ©STERA, Inc. They are shown here with the kind authorization of Barrie Schwortz.
They can be used only for research purpose.
The pictures are shown “as received” although I have used a GIMP filter with the same parameters for all of the pictures to slightly improve the sharpness.
The single image on this blog page is a small piece of the image in Figure 4-1 in the PDF.
If I can find a better way to exhibit all the photographs, I will do so. In the meantime, load up the PDF file and explore. This, at least, should get the conversation going.
