What's the use of digital gray gradient lens?

Bos Ye Zhi Media talks about how to play its role in shooting landscapes and gray gradient lenses.

If you are just beginning to try landscape photography, many people will suggest using a medium gray gradient lens. Like tripods and cameras, this filter is almost standard for landscape photographers.

The medium gray gradient mirror, referred to as ND mirror for short, can control the amount of light entering the local scene, thus achieving the purpose of balancing the exposure of the picture. The tolerance of human eyes is much higher than that of digital cameras. We can see the details of the blue sky and white clouds and the shadows on the ground at the same time, but the camera can't. With the medium gray gradient lens, the picture can be closer to what the naked eye can see. Many professional photographers use this filter.

When you raise your camera to take this magnificent scene, you may find that the sky is pale or the ground is completely unexposed. Exposure difference is based on the horizon, so it is impossible to find a exposure value with the best of both worlds. This is because the camera can't record the environment with strong contrast, and the correct exposure value between the ground and the sky is quite different. It is impossible to "brighten" the exposure value of the earth, so in this case, it is necessary to use a gradient mirror with medium gray level to reduce the brightness of the sky, thus reducing the light ratio between the sky and the ground and recording the details of each area.

The medium gray gradient mirror is somewhat similar to the medium gray density mirror, which can reduce the amount of light entering the lens. The latter is used to darken the whole lens and slow down the shutter speed. Half of the previous shot is a medium gray area and the other half is transparent, which is mainly used to deepen the local highlights in the picture. There are many kinds of medium gray gradient mirrors, which can be divided into hard transition and soft transition. There is no gradient in the hard gray transparent area, which is used to shoot scenes with obvious boundaries between heaven and earth, such as seascape. The commonly used soft over-grey mirror is a gradient medium gray transparent area. Different types of medium gray gradient lenses have different darkening degrees, the most common ones are ND4, ND2 and ND8, which can reduce the shutter speed of 2nd gear, 1 gear and 3rd gear respectively. Bos Ye Zhi Media Company recommended buying a set of 3 gray gradient lenses. The advantage of multiple filters is that they can be superimposed. There are many brands of medium gray gradient mirror, so you can choose the product that suits you.

It is worth noting that the medium gray gradient mirror is not suitable for all landscape photos, because neither the sky nor the ground can be selected. If the horizon is uneven, or there are houses, trees and other objects above the horizon, it will also become dark. When shooting this kind of scene, you can adjust the exposure by post-processing on the computer.

Although the gray gradient mirror has some limitations, the advantages outweigh the disadvantages. In many scenes, it can help you to take excellent landscape photos immediately. If you use this filter well, you can understand light on the next level.
