Final answer:
The daguerreotype photographic process was not a major failure and was actually embraced by the public when it was invented.
Step-by-step explanation:
The statement that the daguerreotype photographic process was a major failure and completely ignored by the public when it was invented is false.
The daguerreotype process, invented by Louis Daguerre in 1839, significantly reduced exposure time and created a lasting result. It became the most popular and affordable photographic method for the general public in the early 1900s. However, the daguerreotype had limitations, such as producing a single positive image that could not be easily reproduced or copied.
