Printing processes involving “transfer” can fall into one of three principal categories. Planographic, in which the original surface is flat. Matrix, in which the originating (or plate) surface is raised. The third is an “incised” surface, such as intaglio.

This triumph of relations hits me as like math operations which can only “increase,” “decrease,” or “leave the same” after action.

yet another breakout:

1. relief
2. intaglio
3. planographic

What is, what isn’t photographable?

The photograph is more “of” something, than it “is” something. Paintings are always “the” thing. In some cases, the photograph is only the thing, just not usually, since the photographer is conditioned by looking, rather than making.
