Neutral density (ND) filters are the most demanded and essential type of photographic filters because of several reasons. For photographers ND filters mean precise control of the amount of light passing through the lens for greater creative control over exposure. For video content creators ND filters help immensely to set shutter speeds to match the frame-rate while maintaining the depth-of-field of the footage.
The HD Mk II IRND1000 is perfect for shooting "imaginary landscapes" or "another world" style images. With a density of 1000 you can easily make a person "disappear" from a cityscape shot, shoot in very long exposure under daytime conditions, or take time lapse videos of moving objects or people to create a movie of fascinating fast streams of movement. Combining ND1000 with the ND64 gives a density of ND64000 that is suitable for directly shooting the sun, e.g., during a solar eclipse, without overexposure and solid colors, while keeping details such as black spots.
IRND technology for even light reduction throughout the visible and IR light spectrum
HOYA applies its signature ACCU-ND technology to the HD Mk II IRND series, guaranteeing an even light reduction throughout the visible light spectrum and up into the higher IR spectrum. This means that there is no leak from the infrared band of the light spectrum, guaranteeing that the image does not undergo any negative affect from color shifts.
ACCU-ND is a benchmark for IR ND technology and makes the HOYA HD Mk II IRND series a market leader for high quality ND filters.
Color shift issue due to IR pollution.
The HD MK II IRND series applies an anti-reflection multi-coating that reduces the chance of any reflections caused by the filter. The coating also comes with water- and oil repellent features which makes cleaning the filter easy and stress free.
The HD Mk II IRND series uses an ultra-thin lightweight, precisely crafted aluminum frame, reducing the chance of vignetting immensely when using the filter with wide-angle lenses. It is also very useful when stacking filters, which can be done thanks to the integrated front filter thread.
