What aperture should I use to shoot the starry sky?

When shooting starry skies, shoot at least 3.5 aperture.

Choose a camera with high sensitivity, so that the effect of the starry sky will be better. The popularity of starry sky photography in the past two years is largely due to the popularity of full-frame SLR cameras. One of the main advantages of full-frame SLR cameras over half-frame SLRs and smaller CMOS cameras is high-sensitivity image quality. Because starry sky photography generally requires ISO 1600, 6400 or even 12800 is also common.

Choice of places to shoot starry sky: You can choose plateau areas or mountain tops with high altitudes and latitudes, open deserts and grasslands; areas away from light pollution and places without cluttered light interference.

1. It can adjust the amount of light entering the lens. For example: the pupils of domestic kittens during the day are always It shrinks into a line, and at night, it automatically opens into a round hole. Therefore, in the same way, when taking pictures, when the light is strong, you need to narrow the aperture, and when the light is dim, you need to open the aperture wide. In other words, the smaller the F value of the camera (other parameters remain unchanged), the more conducive it is to shooting night scenes.

Rotate the adjustment ring on the lens or the knob on the digital camera body to adjust the aperture.

2. Aperture is the most important factor in determining the depth of field. Small aperture (large aperture value) means deep field of field; large aperture (small aperture value) means shallow depth of field. For example: Friends with myopia, if they don’t wear glasses, always squint their eyes to see things more clearly. In photography terms, this is called: narrowing the aperture (pupil), increasing the Depth of field.
