In the article about cameras there's an ilustration showing how to get the X axis from the Z axis, by doing UP cross Z, but the resulting vector points in the wrong (opposite) direction. UP cross Z should point to the right (looking from the back of the camera).
The ilustration for the Y axis has the same issue, but the final Y axis direction is correct because the two issues "cancel out".
