• In 1840 a few independent discoveries discovered that different combinations of chlorine, bromine and iodine fumes could produce daguerreotype plates much more sensitive.

• Improvement in lenses and a charged formula to use silver iodide, which was more sensitive

• By the late 1840’s the Daguerreotype was being used  in the world.

• American Daguerreotypists in particular produced superior portraits by using a technique called galvanizing.

• In 1847 a new negative process produced the niepceotype was published in

• In 1848 Frederick Scott Archer, an English sculptor and amateur calotypist, experimented with collodion

• In 1864 the carbon process patented by Sir Joseph Wilson Swan was universally adopted.
