Manual settings refer to the options available on devices, such as cameras or smartphones, that allow users to adjust parameters like exposure, focus, and ISO according to their preferences. This gives users greater control over the final outcome, enabling them to achieve specific effects or adapt to different lighting conditions. Using manual settings can enhance creativity and improve the quality of images or recordings. For instance, a photographer can set the shutter speed and aperture manually to capture fast-moving subjects or create a blurred background, tailoring the results to their artistic vision.
