Final answer:
Niépce's, Daguerre's, and Fox Talbot's experiments differed in equipment used, objectives, and time period, with each contributing different advancements to the art and science of photography.
Step-by-step explanation:
The experiments of Niépce, Daguerre, and Fox Talbot differed in several ways, so the correct answer is D) All of the above. Niépce's early photographs, like the famous View from the Window at Le Gras, required very long exposure times and were plagued by the lack of image permanence and clarity. Daguerre made several improvements with the daguerreotype, notably reducing exposure times and increasing the sharpness of the images. However, each Daguerreotype was a unique, singular image that could not be reproduced. Meanwhile, in England, Fox Talbot developed the calotype process, which produced a negative that could be used to make multiple photographic prints. This advancement set the standard for future photographic techniques.
