One has to be slightly mad to try what Kurt Moser, AKA . While frankly, quite a few people have gotten bored of the no-risk nature of digital photography, not many decide to skip over 35mm and medium format and go all the way to the ambrotype method of image creation. And it's not hard to see why.
An ambrotype image is a positive large format photograph captured on glass using a variant of the wet plate collodion process. It was introduced in the 1850s, and then quickly abandoned due to being an utterly complex and time consuming process. Let's start with the lighting. You're looking at ISO1. Not 100, not 1000, not 10,000. One. Uno.
Most people who know how to mix the chemicals, prepare a glass plate to be coated with a thin layer of iodized collodion, and then dip it in a silver nitrate solution, are dead by now. Then, there's the issue of having to work with almost zero depth-of-field, yet super high contrast paired with resolution only a NASA telescope can match.
Got the studio part covered? Great! Now, if you need to go outside, you might want to build yourself a mobile darkroom—one that can also work as a full-sized camera. Oh, and since large format photography is all about landscapes and the great outdoors, you might want to built the whole thing on top of a truck that can go literally anywhere.
Like, let's say, an Ural, left behind in Germany by the Russians once the Berlin Wall came down. .
