Filters play a significant role in modifying photographs by altering the light that enters the camera's lens. They can enhance colors, reduce reflections, and protect the lens. Polarizing filters, for instance, can darken skies, manage reflections, or suppress glare. Neutral density filters reduce the amount of light entering the lens, allowing for longer exposure times. UV filters can protect the camera lens from scratches and dust. Therefore, filters are handy tools for photographers to enhance their creativity and protect their equipment.
