Mobile phones will make stars bigger. What's going on here?

To verify, it would be nice to take an image. Pointing at the sky with a mobile phone is a real scene, but because of the low sensitivity of the general mobile phone sensor, the photos taken are "very dark". To shoot stars, sensors need high sensitivity, even digital cameras. It depends on whether the sensitivity of your mobile phone (sensor) can be adjusted to high sensitivity. Exposure compensation has little effect.

To shoot the starry sky, you should first choose a night with good weather conditions, preferably shooting in the wild, which can reduce the influence of urban lighting on shooting. Then turn on the camera, select the professional mode, set the ISO to the highest, and set the shutter speed to about 30 seconds. If the mobile phone supports shooting raw files, turn on this function and put the mobile phone on a tripod to shoot.

Shooting the starry sky requires a long exposure and requires a professional mode of mobile phone. Most Android phones have professional mode, and there are three key parameters that need to be adjusted, namely, sensitivity (about 6400), shutter speed (25-30 seconds) and focusing (manual focusing to infinity). Basically, you can shoot the starry sky with reference to this set of parameters without adjusting other parameters.

In addition, the weather is also very important. Clear and transparent night sky or slightly thinner clouds are very suitable for starry photography. Therefore, it is very necessary to go out to shoot the starry sky in advance and watch the weather.

Most importantly, the shooting location can't be in the city. There are very complicated artificial lights in the city, which will affect the exposure of the starry sky. It is best to shoot in the wild, with less artificial light, and the less light, the better.

Because shooting the starry sky is a long exposure shooting, you need to use a tripod. During the shooting, the phone can't shake. There is often night wind in the wild, so pay attention to avoid the shaking of the mobile phone caused by the wind. Of course, starry sky photography can only be regarded as an attempt for the current mobile phone, and it is good to shoot it. If the quality is high, you still need to shoot with a high-end camera.
