There are several ways to reduce noise in night photographs. The most basic method is to increase the amount of light that is hitting the sensor. If there’s not enough light, noise will fill in the blanks. You can also increase the sensitivity of your camera. Noise is a problem when the subject is in a dark area. Increasing the sensitivity of your camera will reduce the noise, but this method will not work in all situations.
If you’re using a DSLR, the noise that is created by the camera’s sensor will affect the quality of your image. The better-quality images will have less noise. Using a fast lens, or a wide-angle lens, will reduce noise. Fast wide-angle lenses capture more of the environment and are better for low-light performance. These lenses also have less noise natively.
If you don’t want to purchase a new camera, try taking a few test shots in different lighting conditions. Generally, a full-frame camera will perform better in low-light conditions than a crop-sensor camera. Make sure you understand the difference between full-frame and crop sensors. The biggest difference is in the sensitivity of your sensor. In low light, full-frame cameras will produce less noise than a crop-sensor camera.
Noise reduction can also be done in Photoshop. There are many dedicated noise reduction apps that allow you to manipulate the settings. In Photoshop, for example, you can use the Noise Reduction slider to eliminate luminous noise from a picture. If you aren’t a pro at editing RAW files, consider using a dedicated noise reduction app instead. They usually come with more features and control than the built-in noise reduction.
