Ambrotypes are created in much the same fashion as a tintype, except the image is
created on glass. The coated glass plate can be placed in the camera and exposed, or
else exposed under the enlarger using a digital positive.
Traditionally, the ambrotype was viewed in a dark velvet lined case.
The emulsion would be in contact with the velvet, and viewing the image in this way
through the glass, the image would appear the right way - not reversed as in a tintype.
Of course, the ambrotype does not need to be varnished. and black paint,
( or preferably, asphaltum ) can be substituted for the velvet case..
