Hire a screw-on filter HOYA PRO ND4 77mm in Saint-Petersburg
The HOYA PRO ND4 77mm optical filter - a neutral gray filter uniformly reduces the luminous flux by 2 degrees aperture.
Neutral gray filters are designed to evenly reduce the luminous flux entering the camera through the lens. They are used when the shutter speed is not enough to cut off the excess light (for example, when shooting with an open aperture in sunny weather) or when the photographer intentionally needs to significantly increase the exposure time (for example, to blur moving objects).
The HOYA PRO ND4 model is a neutral-gray low-density filter that reduces luminous flux by 2 degrees aperture.
All HOYA PRO ND series filters are made from high quality optical glass from our own HOYA production. The neutral effect is achieved due to the special metallized enlightenment ACCU-ND, which is applied to the glass surface on both sides.
Due to the metallized ACCU-ND enlightenment, the PRO ND series filters do not affect the color balance of images. This distinguishes this series from most similar filters, where the color balance shift is a common problem. Therefore, when using even the densest models of the PRO ND series, the color balance of the images remains almost unchanged.
