The starry sky at night always makes people full of longing and mystery, and iPhone can easily shoot the stars in the night sky.This article will introduce how to use iPhone to shoot stars in the night sky, hoping to help you better record the beautiful starry sky. I. Preparation work First of all, in order to take more detailed photos of the starry sky, you need to use professional shooting equipment. In iPhone, it can be matched with some simple auxiliary devices, such as tripods, shutter cables or remote controls. The tripod can help stabilize the iPhone, and the shutter cable and remote control can avoid the slight shaking when holding it. In addition, the light conditions at night are relatively special. It is recommended to choose the manual mode to choose more suitable shooting parameters. In manual mode, you can adjust ISO, shutter time, aperture and other settings to get clearer starry sky photos. II. Choosing the right shooting environment. Choosing the right shooting environment is the key to taking media photos, and the night sky is no exception.First of all, choose a place that can avoid light damage, such as the countryside or away from the city. This can avoid the light pollution of surrounding street lamps and buildings, and show the deep starry sky. The choice of shooting position is also very important. Try to avoid shooting under artificial light sources, and avoid being too covered with a bright moon. In addition, you should choose sunny weather without clouds or air pollution. Only in this way can we guarantee to capture the most beautiful starry sky. III. Setting parameters. After selecting the shooting position, the shooting parameters need to be adjusted. First of all, set the ISO value. The higher the ISO value, the more noise the iPhone shoots, so try to choose a lower ISO value. Usually around ISO 800 is more suitable. Then there is the setting of the aperture size. The aperture size recommended for shooting at night is F2.Between 8- F4, so that the stars in the photo will be more obvious. The shutter speed is generally between 15 seconds and 30 seconds, which can be adjusted according to the light condition at that time. IV. Manual focus Manual focus is also one of the keys to shooting stars in the night sky. Because the stars in the night sky are very small, the iPhone will automatically reduce the focus depth, resulting in different focal lengths for the whole photo. Therefore, we can solve this problem by manually focusing. On the iPhone, you can manually focus by clicking the starry sky on the screen, or selecting the manual focus function in the camera settings. When focusing, you can use a magnifying glass to see the outline of the stars to adjust the focus position. V. Using HDR mode HDR mode can help us capture more details and present photos more realistically. HD.R mode will take three photos before the shutter is completely closed and combine them to generate a more detailed photo. Using HDR mode can also help us deal with insufficient light and prevent excessive dark or excessive brightness in photos. VI. Post-processing Finally, we can use some post-processing software to beautify the photos taken. Common software include Snapseed, VSCO, Lightroom, etc. You can use these softwares to color or add filters to make photos look more beautiful. In a word, it is not so difficult to use iPhone to shoot stars in the night sky. As long as you have some shooting experience and some auxiliary equipment, you can easily do it. As long as you find a suitable shooting environment and set the camera parameters, you can take beautiful photos of the starry sky.
