The Lee Filter Set Neutral Density Grad Hard is a high-quality lens filter set specifically designed for photographers and filmmakers who seek precise control over the exposure of their shots. These slide-in filters are designed as ND or neutral density filters, allowing for the reduction of the amount of light hitting the sensor without affecting color balance. The Grad Hard filter features a clear transition between the filtered and unfiltered areas, making it ideal for scenes with strong contrast, such as landscape shots with a bright sky and dark foreground. Using these filters can help prevent overexposure while preserving details in the brighter areas of the image. The set is compatible with a variety of lenses and offers photographers the flexibility to achieve creative effects and enhance image quality.
