You have some interesting and innovative ideas, Joe. I'll remember them. I think, though, that since I have a very reliable and simple camera back design for use with film holders, I'll try that first on the prototype to see whether or not the aspect ratio meets my needs and expectations. I'll make a foam core or mat board holder of some sort, I guess, and see how it goes. Can't start it this week, though: the "honey do" list lengthened while I was in Ohio at the recent gathering at John Powers' place.
