However, the Cooke PS945 DOES cover 8x10 at short distances. More on that when I have an 8x10 that can mount the Cooke. As for the Packard shutter, Jim Galli actually built me a front mount Packard shutter, which was not used in these shots, as the Kodak 2D has a behind the lens shutter. I have ordered some wood so I can make a guillotine shutter. I want to see if I can achieve more granularity and higher speed. We will see.. Thanks for looking.
