[split] Jorge's Retracer Thread: darker ink, retracing of text and drawings
One more from page f8r:
   
This clip spans the left end of lines 9-12 of page f8r. It is a composite of the Lazarus narrow-band images MB940IR_012, MB700IR_008, and MB365UV_007 as the red, green, and blue channels.  No processing was done other than scaling each channel to the full 0-1 range.
   
    As usual this clip shows some surviving original (Rt0) ink strokes, several strokes from the general restoration (Rt1), and a few later retracings (Rt2).
   
    Besides the "blue grain" texture, another confounding factor in the interpretation of this clip is that the vellum has horizontal warps spaced ~10 mm apart.  Because of the oblique lighting used, all colors become lighter or darker depending on the slant of the surface at each point.  This effect can be seen in the areas of blank vellum.
   
    (A) Most of this t is Rt0, with small touches of Rt1. (B) The left e stroke of this Ch shows a bit of Rt0 extending from under the Rt1 retrace. (C ) The two e strokes of this Sh are Rt1, the rest is Rt0. (D) The tip of the tail is Rt0, the rest is mostly Rt1. (E) A bit of the Rt0 stroke is visible at the top of each of the i in the aiin. (F) This a had an Rt0 foot connecting to the first i stroke, which was omitted by Rt1. (H) Heads of both ps have at least 5 strokes of Rt1 each.
   
    (J) Glyphs completey retraced by Rt1. (K) Surviving bits of Rt0 show that this glyph was originally a plain o, but Rt1 made it ambiguous, almost an a.
   
    (Q) On this t the lower half of the left leg is Rt0,  the loop and top of the right leg are Rt2 (probably in 3 strokes), and the rest is Rt1. (R,S,T) Presumably Rt2-retraced glyphs.
