I'm intrigued enough to start waving my Visa card around (it doesn't take much).
I see that it's especially targeted to the landscape photographer, but do you have any examples of studio or outdoor portraits made with these?
(Edit: After looking at the author's website, it's unclear to me if his "Slow Portraits" series was made with these or some other medium or a combination. The one portrait in the PetaPixel article is nice but probably not representative.)
Yeah, look through my media here on photrio. I have one or two I took of my kids outdoors that are good examples. Also, if you join the Dry Plate Photographers group on Facebook, you will see other examples. Here:
https://www.facebook.com/groups/1428512583937923/ Giovanni posted more examples there. This is sort of the "ground floor" of getting them out to the public so there aren't many. But there are some... made in studio with flash and outdoors. Just shuffle through the group, and feel free to ask questions there. I don't have a lot because I'm more of a landscapist than a portraitist (I made those words up lol ).
How fast an ISO could you make a dry plate if you were not interested in replicating 1880's technology? ISO100? 400?
I could get this emulsion to ISO 25 or so. Speeds beyond that starts to cause problems (peppering, grain, etc) which preclude pushing it faster. Faster emulsions require a different recipe and the equipment to keep the house from stinking up with ammonia. In any case, really fast emulsions are on my list, but not at the top.
I can't stress enough that a goal of this venture is not only to make plates available, but to also fill the gap in the evolution of historical processes that Kodak and others have left behind and which, unlike wet plate, hasn't grown a huge following like it should have. Filling that gap is my current focus.
