Manual Focus

Definition

Manual focus refers to the process of adjusting the lens of a camera by hand to achieve the desired sharpness and clarity in an image. This technique allows filmmakers and photographers to have complete control over which part of the scene is in focus, ensuring that they can creatively dictate the viewer's attention. Manual focus is particularly important in various camera types and plays a significant role in controlling exposure, focus, and white balance effectively.
