I really can't remember the details of this shot. It's been a while.
But I had one snooted flash coming from the left, somewhere. I don't remember what settings or which flash it was. The ball was on my dresser, which is cherry and very reflective.
And just to the right of the ball, out of the frame, is a large mirror that is attached to my dresser. So the specular highlight is actually a reflection of the actual light.
