ON THE LEFT SIDE OF THE IMAGE BELOW:
After carefully tilting plate "H", a camera was used to record two views of the negatively-reflecting daguerreotype surface. The castellated tower in the images on the left shows as "dark".
ON THE RIGHT:
Software "inversion" of both images shows the contrasting positively-reflecting surface.
The castellated tower is now "light".
