Wet plate collodion on black glass.
After pouring some collodion last weekend in Calif, I had a big itch to get out and pour some plates. Spent saturday morning out making a few 7x17 ambrotypes in downtown Austin.
These are great. It appears you decided to disregard my useful tip about sticking your thumb in the corner of the collodion on the plate by accident. Still, it is a very beautiful picture even without a disfiguring thumbprint.
