The bullino style engraving creates it's image by shadow…
By changing the pressure and the angle that the graver makes with the surface of the work, those burrs can be manipulated in depth and size. This produces differing shadow effects. Add to that then how closely those burrs,,or 'dots' as they are often called,,are placed together and you can get anything from Black all the way to White and anything in between on the Gray scale for 'color'.
On the buckle buffalo that I mentioned above the background is black. I could not conceive how Fracassi could produce that without colorizing. Now I can. Thanks.
