Why does slow-motion photography flicker? Is it normal?
Usually, the fast motion in movies is because the lens is below 24 frames per second, while the slow motion is above 24 frames per second. Under such special effects, the motion on the silver screen can be slowed down or accelerated at will, resulting in a special viewing effect.
Moreover, it affects the structure of the angle single-lens reflex camera, which determines that it is completely focused through the lens, so that the image seen in the observation window can always be the same as that on the film.
Extended data:
Another major feature of a single-lens reflex camera is that it can replace lenses with different specifications. People's psychological feeling, especially slow motion, has become a common expression skill in film and television art because of its direct charm in expressing rhythm and emotion. Tracing back to the source, the fundamental function of slow motion is to prolong the actual movement process.
The instantaneous change is delayed and amplified, so the main action is particularly emphasized. So slow motion is considered as "close-up in time". This time, "enlargement" combined with narrative foreshadowing created a profound artistic conception.
