H&Y K-Series HD MRC Center GND Filter ND1.5
The 100 x 150 mm K-Series Centre Graduated Neutral Density 1.5 filter from H&Y Filters is a rectangular filter that can be used to darken the sky, particularly along the horizon, during a sunrise or sunset, while keeping the exposure in the rest of the image normal and unchanged. This filter achieves its effect through a density band of 1.5 in the centre, which reduces light entering the lens by up to 5 stops. The density band extends towards the top and bottom of the filter, then tapers off towards clear areas at the upper and lower edges of the filter.
A density band of 1.5 with clear zones directly above and below means this 100 x 150 mm K-Series Centre Graduated Neutral Density 1.5 filter mimics the position of the sun when it is at or just above the horizon. In such situations, the sun tends to appear closer to the centre of an image than to the upper edge, with an increase in brightness that is far more prominent on either side of the sun than above or below it. This brightness pattern corresponds to the density pattern on the filter.
The 100 x 150 mm K-Series Centre Graduated Neutral Density 1.5 filters are made from Gorilla Glass for enhanced scratch resistance, increased clarity, and colour fidelity. Each side of this filter features eight layers of anti-reflection coating to prevent internal ghosting and reflections, as well as an anti-smudge nano-coating for improved water and oil repellency, making cleaning easier.
The 100 x 150 mm K-Series Centre Graduated Neutral Density 1.5 filter comes with an H&Y Filters 100 x 150 mm magnetic quick-release filter holder, compatible with an H&Y Filters 100 mm K-Series filter holder. When used in combination with a 100 mm K-Series filter holder featuring two magnetic filter slots, filters with a magnetic filter holder can be magnetically stacked in front of the camera lens, rather than being limited to a specific number of slots in the filter holder. This allows the user to decide how many filters to use, which can then be quickly installed, repositioned, or swapped out for different subjects or changing lighting conditions.
During use, the forward-facing rulers on the sides of this magnetic quick-release filter holder assist with accurately positioning the 100 x 150 mm Centre Graduated Neutral Density filter relative to other filters it is stacked with. This perfectly complements the use of the 100 x 150 mm Centre Graduated Neutral Density filter, whose effect can be adjusted to suit changing lighting conditions or creative requirements by moving it up or down. The magnetic quick-release filter frame also reinforces the edges of the 100 x 150 mm Centre Graduated Neutral Density filter, increasing the rigidity of the filter and promoting sharp results by keeping the filter lying flat. A filter pouch for storage and transport, as well as a Microfibre cloth for filter maintenance, are included.
