The Wet Collodion is a photographic technique from 1850 created by Frederick Scott Archer (1813-1857). This process, very close to the daguerreotype, is used for photography on glass or metal, in a liquid (wet) state during the entire taking and developing process. Its use lasted approximately 30 years. It was recovered and has been used again today since the early 2000s. This selection of portraits includes artists, photographers, friends, and family.
