[split] Jorge's Retracer Thread: darker ink, retracing of text and drawings

[Jorge_Stolfi]

By "smaller area", I meant the symbol in question + the text immediately around it, not just the area containing only those marks. For example: You see that both the eva t (to the bottom left, and the bottom middle) are aligned, along with many other symbols.

Yes, indeed, in that image the flipped You are not allowed to view links. Register or Login to view. text aligns very closely with the seethrough on f116v.

Which image are using for the latter?  On the UV image, which I have been using, there is hardly any seethrough.  Is that a red or infrared image?

And I'm not sure about matching the image using the holes either. This would only work if the parchment is uniform, which it is not. When matching via the holes it becomes quite clear that you will not be able to match all of the text this way. I highly recommend trying your exact process on the multispectral scans, if possible.

Yes, the non-linear distortion due to vellum curvature will cause errors, because the holes are all near the edges. 

Could someone visit Beinecke, and, when the Librarian is distracted, pull a Dremel out of the pocket and drill a grid of fine holes, one cm apart, all through the whole book? As preparation for future scans? 

All the best, --stolfi
