The 39mm ND8, ND64, ND1000 Lens Filter Kit from Urth is a versatile set of screw filters designed specifically for photographers looking to expand their creative possibilities. The neutral density filters (ND filters) allow for precise control over the amount of light reaching the sensor and are ideal for various lighting conditions. With the ND8, ND64, and ND1000 filters, you can extend exposure times to create motion blur or open the aperture for a shallow depth of field. These filters are available in a compact 39mm format that easily attaches to most lenses. They are particularly useful for landscape and portrait photography, as they help optimize lighting conditions while maintaining image quality. The kit provides a practical solution for photographers working in both bright and changing light conditions.
