Product Description

Product Description:ND filter, is a kind of camera lens with additional filter. Neutral Gray Mirror, also known as Neutral Gray Density Mirror, or ND Mirror for short, is a piece of gray, pure and transparent advanced optical glass. Its effect is to reduce exposure by reducing the amount of light passing through the lens. This filtering effect is non-selective, that is to say, the ability of the ND mirror to reduce light of different wavelengths is equal and uniform, and it only reduces the light, but does not affect the color of the original object. Any effect, so the contrast of the scene can be reproduced realistically, and the same applies to color photography and black and white photography.

There is also a special kind of ND mirror called gradient mirror. Among them, the most widely used is the neutral gray gradient mirror, referred to as GND mirror. It is half transparent and half light blocking, blocking part of the light entering the lens. It is an essential filter for landscape photography. . The GND mirror is used to balance the contrast between the upper and lower parts of the screen or the left and right parts. It is often used to reduce the brightness of the sky and reduce the contrast between the sky and the ground. In addition to ensuring the normal exposure of the lower half, it can effectively darken the brightness of the upper sky, make the light and dark transition of the work soft, and effectively highlight the texture of the clouds.

Product function:
1. Reduce the amount of light. For example, if it is difficult to use a large aperture to shoot in a place with strong light, you can add a neutral gray filter;

2. Extend the shooting time, such as shooting foggy water in a very bright place;

3. When shooting street scenes during the day, adding a certain number of neutral gray mirrors can greatly extend the exposure time to blur pedestrians or even completely remove pedestrians and vehicles.

The ND filter only reduces the intensity of the light, so it does not affect the color of the final image, nor does it affect the camera's white balance and automatic exposure. Using an ND mirror will not have any effect on the color and contrast of the subject. In addition, since the SLR camera is metered through the lens, the ND mirror will not have any impact on the camera's automatic exposure system.

The ND lens is a very practical additional lens when it is necessary to artificially use a slow shutter speed, or to reduce external light. Of course, due to the different calibers of different lenses, ND mirrors also have different calibers. When using, you need to choose ND mirrors with different calibers according to the diameter of the lens.

The difference between the use of ND filter and ND filter:
1. The neutral gray mirror is generally coated with a uniform gray coating on the lens, which is mainly used to reduce the exposure of the camera. When the light of the subject is bright, the neutral gray mirror needs to be used to reduce the exposure.

2. The medium gray gradient mirror is a half gray medium gray mirror. The medium gray gradient mirror will not change the color balance of the picture, but it can change the contrast of the photo. When taking landscape photos with the sky, the EV values of the sky and the ground are often different by several stops of aperture. Either the sky is overexposed or the ground is not underexposed with details. Gradient gray can effectively solve such problems. Adjust the direction of the gradient distribution by rotating the outer frame of the lens, block the gray part in the position of the sky, reduce the brightness of the sky, and balance the exposure difference between the sky and the ground. At the same time, it can darken the sky and highlight the clouds., is a kind of camera lens with additional filter.
