Ambrotypes are under exposed negatives that appear as positive photograph. The black or clear glass plate is coated with collodion with added salts, light sensitivity is created by “dipping” coated plate into silver nitrate bath. The plate is exposed in camera and processed in a darkroom before the plate is dry. Each photograph is unique – “one off”. When protected with varnish they have an enduring life.
