Ambrotype. I found out that if you want to make a glass negative you need 3x exposure and roughly 2 minute development. If you're making ambrotype positives the exposure is the same as with tintypes. You mount with felt to give the image its blacks.
The colloidion has held onto the glass perfectly. I am happy. I may switch to ambrotype only because the image quality is even better. Washing glass is kind of painful, but we do anything and everything for image quality over here.
