These are whole plate tintypes using Johns 10×12 camera with an insert.
As the day progressed we changed which camera each of us had been using, so we had the opportunity to pour and shoot different size plates.
The very last plate was late afternoon and a good 40 second exposure as the UV light was dropping fast. I over developed a little just to make sure. And yes that is an armadillo.
So what next. I have to finish clearing out the spare bedroom to use as a darkroom/studio, get the chemistry and accessories and away we go.
