Detail on NHD27 Luxuria by Bruegel

<p>Detail on NHD27 Luxuria by Bruegel, paper (drawing SII132816 &amp; print SII22656, both &copy; KBR, Brussels). The drawing (A-E) has been imaged with the MS PLD; the print (F) with the WL PLD. (<strong>A</strong>) Standard color representations of the detail on the drawing, the red and green indicators evidence the position of the virtual incident light sources (i.e. albedo); (<strong>B</strong>) Normal map based on the IR dataset, the indentations are slightly recognized, the blue profile lines of the surface reveal the estimated depth of the indentation lines; (<strong>C</strong>) Surface with texture map, revealing all indentation lines, the underlying normal map is based on the UV dataset; (<strong>D</strong>) Normal map based on the UV dataset, all indentation lines are accurately recognized by the system; (<strong>E</strong>) IR texture map with underlying UV dataset normal map, with sufficient raking light an excellent representation of the indentation lines can be achieved;&nbsp; (<strong>F</strong>) Same zone on a print (mirrored), revealing some slight shifts of the bird&rsquo;s contour lines compared with the indentations on the drawing.
