After taking many landscape photographs, besides wide-angle mirrors and cameras, I found that one of the accessories that will always be in my camera backpack is Gradient Grey Filter (GND). What is the power of this seemingly flat filter? Why use it? After reading this article, I hope that all students will also consider starting a piece, so that your ability to shoot landscape photographs can be further improved!
Gradient grey filters can add a sci-fi effect to your photos.
What is Gradient Gray Filter (GND)?
Gradient gray filter is a circular or square film/glass. The surface is coated with a gradient coating from transparent to gray. The gray part can block a part of light from entering the lens. Therefore, different parts of the photo have different exposure values at the same time.

With gradient grey filters, details of the sky and land can also be preserved.
If there is no gradient grey filter, the flowers in the foreground will be dimmed after the sky level is preserved! ____________
Under what circumstances do gradient grey filters need to be used?
Gradient gray is often used in the following situations:
1. Sunrise/Sunset 2. Beach/Coast 3. Photographs of the sky and ground during the day 4. Keep some light level details in the photos.
To sum up, if you see that the ambient light difference you want to take is large, and the photograph can only show some details (only dark or light details), then you should consider using gradient grey filter. As you can see from the following picture, if you don't use gradient gray filter (top), the land will be dark after keeping the sky details. After using the filter (bottom), the light difference will be balanced, which makes the image more detailed! __________
Skills in using gradient grey filters
Gradient grey filters are very easy to use. Just put the appropriate filters in front of the lens and cover the light position with the grey end. The bigger the optical aberration (such as in the fierce sun) the thicker the filter (such as ND16). Normally, ND4 or 8 is enough. Otherwise, the photo will be taken like "HDR" or half of the photo will be changed. It's too dark. In a word, remember to feel natural when you take a picture. Only in this way can you use the gradient grey filter effectively. Let's put a gradient grey filter of ND4 and ND8 in our backpack today. Let's see the difference next time we shoot.
Using gradient grey filter + slow shutter, you can photograph clouds and silk water in the sky!
