The two illustrations both show the same section of the painting – the section at the left with the lady visitor. The black-and-white image on the left is the X-ray image. In the completed painting, seen here on the right, the woman is leaning against the window and gazing down at the child. Her flesh tones have been created with the addition of lead white pigments. Since these pigments absorb the X-rays, they appear bright in the X-ray image. Two earlier versions of the visitor are discernible: neither the standing figure nor the one seated at the table looks into the room, but rather out of the window. The X-ray moreover reveals that there were originally two baguettes on the table where we now see a single loaf of bread.
