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

[oshfdk]

• Two glyphs in the middle text ring are somewhat darker than the surrounding ones:  an <l> in the word <lsheotey> and an isolated <o> next to the "notched square" delimiter.  Several other words appear to be retraced, and several glyphs are misshaped to some extent (4,5).
  

This l from 71r (snippet 5) does look significantly darker in red/IR, but I see no evidence of any obvious previous shape, no obvious double strokes or anything like this. The below is the contact sheet of all MSI channels for this l. I don't know why it's darker specifically in IR/red channels and looks almost the same as the rest of the text in UV. It just looks as if this whole text was only written once, but one particular letter got a much redder/darker portion of ink. Maybe the letter itself was written out of sequence.

   

The word <otodal> at 12:00 on the middle text ring is darker than surrounding ones, so it may have been written out of sequence.

I won't post the whole sheet for otodal, it's rather unremarkable, but what is interesting is the patchy appearance in near IR below (780 and 940 nm, if the filenames mean what I think they do). So it looks like the ink had a lot of irregularity, which could explain why some strokes are darker than the others.

   

(Edit: forgot my usual disclaimer: I know nothing about multispectral photography, so my interpretations are not to be taken for granted.)
