It was once said that "all roads lead to Rome". If you were to ever to trace your genealogy in the learning of wetplate collodion, it is very likely that these roots wind their way back to New York state. This week's episode is a little different than most in that I have not one, but two guests that share their experience and learnings with others all over the globe. France Scully Osterman and Mark Osterman have been involved with researching, practicing and teaching a multitude of historical photographic processes for decades. I'm really grateful to these two for sitting down and sharing some great stories about their impact in the world of collodion.
