And I can vouch for Hugo's wet plate holders! I have three (4x5, 5x7 and 8x10) and they are so well engineered that they make handling plates almost effortless. I have a converted 8x10 film holder (made into a wet plate holder) and it is far less pleasant to use: it is always a struggle to get the job done with it. The Chamonix holders are far easier to work with. Five stars for Chamonix holders!
