Ideas for Framing Ambros for Exhibition

Been thinking on framing for the possible 2008-09 AMBROTOS KANATA exhibition. 

How to proceed? Diptych’s? Ambrotype sizes? Types of frames? How many?

Here is a 14x14 inch ambrotype in a hand made pine frame. The black substrate behind the clear glass ambro is only a test 11x14 inch metal plate.

I currently thinking of going with 11x14, 14x14, 20x24 and 24x24 ambrotypes in large hand made wooden frames.

This diptych frame looks pretty good.
