Any conservator will tell you that one way to check on damage or over-painting is to look at a canvas under a raking (angled) light. And that’s what someone should have told Arnold Schwarzenegger when he unveiled his official Governor’s portrait. That big smudge is a clumsy patch-up blotting out an image of the Governor’s ex wife who’s portrait appeared on a small lapel pin when the painting was originally commissioned. You would have thought that of all people Schwarzenegger would have known that lighting is all.
