IDLA Digital Photography Practice Test

Calotypes had the primary advantage of being able to create multiple prints from a single negative. This was a significant development in the history of photography, as it allowed photographers to reproduce images easily and share them with others. Instead of having to produce a unique, one-off image as in the Daguerreotype process, which captured a singular photograph on a polished metal surface, the Calotype process utilized paper negatives. These negatives could then be used to make many positive prints, greatly enhancing the accessibility and distribution of photographs.

This ability to produce multiple copies fundamentally changed the way photography could be used, promoting its use in journalism, art, and personal correspondence. It laid the groundwork for modern photographic practices where creating multiple prints or digital copies from a single image file is standard. The other options do not reflect the primary advantages of Calotypes over Daguerreotypes, focusing instead on aspects such as exposure time, handling, or color technology, which were not the defining features of the Calotype process.
