A process where the photographic chemicals are applied to a glass or aluminium plate by hand, exposed in a plate camera, and developed before they dry.
The images resulting from this process can be ambrotypes on clear or black glass, glass negatives or tintypes. Although quite a demanding, expensive and lengthy process, wet plate collodion technique is gaining back its popularity among photo artists.
Extreme sharp photos, but with an immense blur outside the center. Colors look strange, because the chemicals react to UV light: red becomes black, blue turns to white.
