The x-ray in the centre shows the texture of the panel, which has been thinned from the back. The face, hands and cuff, all contain lead white and show up very clearly, as does the cup of the scales containing the book, because of its halo of lead-tin yellow. Some of the modelling and brushwork in the jacket can be faintly detected in the sleeves in the x-ray. The image taken in ultra violet light on the right shows the relatively good condition of the face and hands.
