How does Canon 5d4 shoot the starry sky?

1. Find a suitable shooting location and shooting time: choose a plateau area with relatively few clouds or a hilltop highland to ensure that there is no unnecessary artificial light interference around. The best time is 9: 00 to 4: 00 a.m. on a moonless sunny night in summer and autumn.

2. Use the mobile phone map software or compass to find the brightest Polaris, and shooting in this direction can ensure that the star orbit is a relatively complete ring.

3. Change the 5D4 lens to manual focusing MF, adjust the focusing ring, turn the camera lens to infinity (if there is a focal length scale, you can see the sign of infinity, if there is no focal length scale, you can turn it to the far end and then turn it back a little), turn on the maximum aperture and ISO (lower it later), and zoom in to the maximum in live view mode to ensure the clear imaging of stars.

4. Set the 5D4 shooting parameters to ISO 100, the aperture F4 (or less) and the shutter time to 20-30 seconds. You can take a picture according to the scene environment to ensure accurate exposure before the official shooting begins.

5. Connect the electronic cable to 5D4, and set the digital shooting interval and the number of pictures. If you need to shoot for more than 2 hours, you'd better use two batteries with an extended handle to shoot at the same time (if you need to replace the batteries, be careful not to change the camera position, otherwise it will affect the later synthesis).

6. Check whether all the pictures are exposed normally (if necessary, you can use Camera Raw or Lightroom for batch color matching), import the photographed pictures into Photoshop for stack processing, click File-Script-Load the files into the stack in turn, browse and load the filtered pictures, select Layer-Smart Object-Stack Mode-Maximum, and wait for PS to automatically process them.
