As in the Portrait of Thomas Haaringh (B. 274) (See Lot 79), Jan Lutma is a study of introspection and ageing. Although portrayed with his tools and an example of his own work, the viewer's concentration is drawn to the features of Lutma himself.
The quiet character of the face is emphasized on the shadow cast on it's right side which is in strong contrast to the blank source of light which comes from behind and above him to the right. In the second state, this open quality is altered by the introduction of a window setting.
