Figures from McCrone Pigment Analysis?

[proto57]

These photos have a resolution of 72x72 dpi. This resolution cannot be classified as microphotography.

I get what you are saying, and they are certainly not high resolution. But I think the point is the magnification... that they are demonstrating, at high magnification, the areas from which they took the samples.

But still, I was also surprised that the magnification was not very high. The purpose was different, I suppose, but when McCrone made photomicrographs of the inks of the Vinland map, it was far higher... you could see the shape of the crystals of the components of the ink:

   

Whereas these Voynich "microphotographs" are far, far less magnified... I'm not sure the power of magnification is recorded anywhere, but obviously not anything like the above image for the Vinland Map. In this case, the "4o" width would be about 4mm, according to the scale.

   

Also, though, the 72x72 resolution of the report images may not be anything like the original images which McCrone took. These were probably reduced for use in the report, as, again, if my guess is correct, the only purpose of these "microphotographs" was to show, in adequate detail, where the sample was from.
