What is the purpose of using a lens filter in video production?

Using a lens filter in video production primarily serves to modify the light entering the camera. Filters can achieve various effects, such as reducing glare, changing color balance, or enhancing contrast. For instance, neutral density filters limit the amount of light without affecting color, allowing for wider apertures or slower shutter speeds, which can create a specific aesthetic in motion blur or depth of field. Color filters can also be used creatively to change the mood or tone of the captured image. This adjustment can substantially influence the overall quality and appearance of the footage produced during video production.
