The images produced by Dagurreotype were positive images that were recorded on copper plates coated with silver iodide.

The images produced in camera were developed by exposing them to mercury vapor and then fixing it by strong salt solution.

Daguerre sold his process to the French Academy of Sciences for an annual pension.The process was announced on 7th January 1839 and  on 19th August all the information about the process was shared with the world for free but not to Great Britain. In Great Britain Daguerre's agent filed a patent.
