Here's a fascinating video about a wet plate camera built into the back of a truck and which takes enormous collodion photographs.
Collodion is a process I don't know too much about and I doubt I'd have the patience to get heavily involved in it. However, it has to be said that good collodion photographs, particularly portraits, are absolutely stunning.
I loved this quote from the video, "When I started in photography, I was using my hands to create images. And it seemed like overnight digital came and all that came to an end. I didn't know it at the time, but I lost something I loved." That mirrors my experience exactly. Here's another great quote, "I didn't just build a camera: I created a time machine".
The guys in this video deserve respect for this endeavour - it really is quite incredible when you think about it.
