thanks that is helpful. I have a Zero 6 X9 that is fun. This is great fun to "clean out the cobwebs". Several of my students do a lot of 4 x 5 images on a handmade camera we loving call the "bird House".
THere is another Art Center in town that has a weekend session making a 4 x 5 camera. They are really lovely and well finished. I have thought about building one just for fun, but it doesn't make sense as my equipment list is tooooooo long . Hard to use what I have now let along making something.
