NHK, a Japanese broadcasting corporation, incorporates images of disasters, accidents, and natural phenomena captured by viewers in their news and other programs. This allows for a more diverse and authentic representation of events, as viewers can capture footage that may not be accessible to professional journalists. NHK encourages viewers to share their photos and videos taken on smartphones or digital cameras, providing a platform for citizen journalism. By utilizing viewer-submitted content, NHK is able to provide a more comprehensive and accurate portrayal of events.

To ensure the quality of viewer-submitted content, NHK recommends the use of a spirit level function on cameras to recognize the level of the camera. This helps to avoid tilted or skewed images, ensuring that the footage is clear and easy to understand. Additionally, NHK offers an animation photography lecture for beginners, providing tips and techniques for capturing high-quality footage. By providing resources and guidance for amateur photographers, NHK is able to maintain a high standard of content while still incorporating viewer submissions.

Overall, NHK's use of viewer-submitted content allows for a more diverse and authentic representation of events.
