Make your sunrise and sunset photography stand out with the high-quality SW150 150x170mm Reverse-Graduated ND 0.9 Filter (3 Stops). This durable and versatile filter is a must-have tool for landscape photographers seeking to master exposure control during the golden hours of the day. Designed by the reputable brand, Lee Filters, this reverse-graduated neutral density filter is specifically crafted to provide full control over your images during the start and end of the day. Its unique design features a stronger density in the center of the filter, transitioning smoothly to the edges, ensuring a natural, balanced exposure to the sky. The filter's 0.9 density (3 stops) effectively reduces the amount of light entering your camera lens, allowing for a wider aperture or slower shutter speed in bright conditions. This feature is particularly beneficial for seascapes, where the sun at the horizon line is at its brightest. Unlike other filters that may leave a harsh 'stripe' at the horizon line, the SW150 150x170mm Reverse-Graduated ND 0.9 Filter ensures a smoother, more gradual transition between the dyed and clear areas of the filter. This results in a pleasing and balanced image that truly captures the beauty of your surroundings.The filter is non-coated, allowing for a more natural color rendition, and is most effective when used on lenses of 24mm or wider on a full frame DSLR (or equivalent). For optimal results during sunrises and sunsets, simply slide the filter in the holder to position the most dense area on the horizon line. Hand-manufactured by skilled technicians at Lee Filters' Andover factory, this filter exemplifies precision and quality control that's unique in the industry. Elevate your photography with the SW150 150x170mm Reverse-Graduated ND 0.9 Filter, and capture the world in its most stunning light..
