I have two coating questions (after reading Bob Shanebrook's book). 1) Why would one ever prefer a shiny overcoat vs matte? It is a really annoying characteristic of TMax films for example. 2) With a tabular grain emulsion, how do they get the flat grains oriented after the emulsion curtain pours onto the base? In a cross section of TMax, you can see the flat grains all lying pretty uniformly in the right orientation. I can't figure out how.
