How to use filters in night photography

Lead: Filters can show various effects in night photography. Let's take a look at the application of filters in night photography.

1. starlight mirror. The filters of Gaojian series 055, 056, 058 and 059 can form different starlight effects. In addition, some other filters can also be used for night photography, such as the REF059 soft cross mirror built by Gao Jian.

2. Soft lens. Soft lens was originally suitable for shooting some scenes with a certain contrast between the background and the main body, so it also played a certain role in shooting night scenes. With the soft lens, the dividing line between light and dark or bright subjects in the night scene can be diffused into the night sky, which is quite strange.

3. overspeed mirror. For example, the 2 17 overspeed mirror of Gaojian series has a rising feeling, and the image is half bright and half dark, elongated, as if it were a fast-moving object. What if it will? Speeding? If this part is placed at the bottom of the scene, there will be an effect that the upper part is clear and the lower building rises upward in the night sky.

4. rainbow mirror. Generally, rainbow mirror is suitable for shooting the content of strong point light source in the picture. The concrete effect is that there is a bright spot in the middle, surrounded by rainbow-like light. But it should be used according to the actual situation of the picture, so as to avoid abuse and painting a tiger into a dog.

5. Multi-prism. The main function of prism is to refract a simple object, so that several identical objects appear in the picture, just like looking at the scenery from a kaleidoscope. However, the filter also has its shortcomings, that is, the imaging quality is poor and the picture is easily confused.

6. The role of biased votes. Polarizer is used to eliminate polarized light, so as to improve the color saturation in the picture and eliminate the reflection of non-buildings. When shooting at night, the scene light can be obviously dimmed, and the photographer can choose a lower shutter speed. By extending the shutter speed, the exposure time can be increased, so that the film can have enough exposure time for the running lights to form a stripe effect, and at the same time, some bad reflections on the glass can be eliminated.

7. Gradient mirror. The gradient mirror is half colored and half colorless. Gradient mirrors are mainly used to adjust the contrast between the upper and lower parts of the scene. When shooting night scenes, if it is still early and the sky brightness is too high, you can darken the sky with the help of a neutral gray gradient mirror. When the sky is getting dark, you can change the color of the sky with gradient mirrors of other colors, and so on.
