1、OPTICAL GLASS: The filter set adopts excellent lens grinding process, great physical properties to make the imaging clearer, so that your photographing works more professional. 2、MAGNETIC ABSORBENT CONTAINER: With storage case, built in silicone inner tray for scratch protection. The magnetic design allows the filters to be securely attached to the filter case, preventing the filters from falling apart during bumpy journeys. 3、ND FILTERS: Used to reduce the amount of light entering the camera to avoid overexposure, and used to block scattered light to improve the color saturation of the picture. They can also be used to achieve special effects with slower shutter speeds, such as capturing misty flowing water or light trails at night. When photographing video in harsh sunlight, ND filter can lower the shutter speed for a comfortable amount of motion blur. 4、CPL FILTERS: Used to eliminate harmful non metallic reflections, deepen the blue sky, and enhance color intensity to improve image clarity and visual impact. They are commonly used when capturing scenes behind glass, clear bodies of water, or underwater objects. 5、MCUV Filters: When photographing in expansive environments (mountain, vista, high altitude) with high color temperatures, where images may appear overly blue due to increased blue wavelength and UV components. By reducing the blue and blue gray tone caused by UV light, MCUV filters enhance image clarity by increasing light transmission.
