What if the night scene shooting is full of noise?

There are often many problems in shooting at night. If you don't know the camera parameters, you may use the camera's P file to shoot, so the camera is really easy to operate, but what you shoot is not so good. P file is really a good choice when shooting during the day, but what you shoot at night is a picture full of noise ~ what is noise? Let's talk about it

The noise suppression ability of digital cameras has always been one of the factors to evaluate the quality of cameras, and images with more noise will be rated as poor quality; Cleaner images are considered to be of better quality. In fact, the noise of digital images looks very similar to the particles on the film, but they are two different things in their bones. Noise in digital images is inevitable, even if the photographer covers the lens to shoot, there will still be some noise in the image; When photographers use high sensitivity to shoot images, noise is more obvious. When shooting at night, because of the light, we will improve the ISO of the camera at this time. At this time, the noise driven by high ISO mode will naturally be generated accordingly. In order to reduce noise, ISO can only be reduced moderately, which can not only give the camera a certain amount of light but also reduce the corresponding noise. At the same time, we will also reduce the shutter speed accordingly, and set aside a certain time for the camera to receive a certain amount of light for shooting during the shooting process; In addition, the aperture will be increased accordingly, so that the picture will be brighter accordingly.

Usually I use these three methods to make the night scene look better and have less noise. But if you can't adjust the camera parameters, you can only use another method-post-processing. Take photos according to your original method, and finally export the photos and put them on Photoshop for modification. But actually, in most cases, I prefer the first method. Adjusting camera parameters is simple, convenient and quick, and it is also a kind of respect for my camera.

The above are suggestions on how to deal with the noise problem in night scene shooting. Do you have these simple noise reduction methods? I wonder what other noise reduction methods you have? For more film and television production related content, you can also pay attention to this platform!
