Questions: Which would best be described as photography's most important contribution to Science? Griffiths editing processes Eastmen's Celluloid Film Photo Journalism Muybridge's Motion Studies

The answer is Muybridge's Motion Studies.

Explanation for each option:

1. Griffiths editing processes: This option refers to the film editing techniques developed by D.W. Griffith, which are significant in the history of cinema but not directly related to a scientific contribution. Therefore, it is not the best choice for photography's most important contribution to science.

2. Eastmen's Celluloid Film: George Eastman developed celluloid film, which was crucial for the development of photography and motion pictures. While it had a significant impact on the accessibility and practicality of photography, it is more of a technological advancement rather than a direct scientific contribution.

3. Photo Journalism: Photojournalism is the practice of using photography to tell news stories. While it has had a profound impact on media and society, it is not primarily a scientific contribution.

4. Muybridge's Motion Studies: Eadweard Muybridge's motion studies are considered a major scientific contribution because they provided a new way to study and understand motion. Muybridge's work involved capturing sequences of images that showed the movement of humans and animals, which was groundbreaking in the fields of biomechanics and physiology. His studies laid the groundwork for the development of motion pictures and contributed to scientific understanding of movement.
