An essential tool for photographers aiming to capture the perfect sunrise or sunset, the X-pro 100x150mm Reverse GND8 Square Filter is expertly designed to balance the intense light emanating from the horizon. This filter is particularly effective when the light is most concentrated in the middle of the frame, gradually fading towards the edges, ensuring that the brightest area remains around the skyline without overpowering the rest of the image.Crafted with premium Agc optical glass, this filter boasts a double-sided 28-layer coating that significantly enhances its performance. The anti-reflective Green Film is a standout feature, effectively minimizing surface reflections and reducing glare. This is especially beneficial for photographers using long-exposure lenses, as it helps maintain the pristine quality of the captured image.
