It was the only 19th-century photography technique that was not based on expensive silver halide chemistry but was still sensitive enough to use in a camera, with exposure times comparable to those of the daguerreotype and calotype.

When the French Academy of Sciences announced the invention of the daguerreotype on 19 August 1839, Pucher quickly mastered the process, but it was too expensive, so he developed his own way of making photographs.

[citation needed] While living in Bled, Pucher met a French viscount, Louis de Dax, who wrote about him in the Parisian magazine La Lumière.

The advantages of Pucher's procedure included a shorter exposure time (15 seconds, which allowed him to make portraits), a positive image, and the possibility of reproduction.

Pucher was not the first to try to create photos on glass: A Frenchman, Abel Niépce de Saint-Victor, reported his own invention to the French Academy of Sciences in 1847.

A yearlong program of events in Slovenia and abroad was organized in cooperation with many municipalities and institutions to celebrate the 200th anniversary of his birth.
