A Michael Sweerts, A Game of Draughts, 1652. Oil on canvas, 48.6 × 38.1 cm. Mauritshuis (The Hague), inv.no. 1121. Image courtesy of the Mauritshuis Museum. Photography by Margareta Svensson. B Infrared reflectogram, showing a halo around the head of the little boy in the center of the composition. Infrared reflectography by Julianna Ly. C–F Elemental distribution images from MA-XRF. C Pb-L map. D K–K map. E Fe–K map. F Mn–K map. MA-XRF can successfully visualize hidden halos. From the different maps, it can be concluded that each halo seems to have been painted with a slightly different paint mixture, as the signal intensity of the elements differ from halo to halo
