Detailed explanation of galaxy shooting method

Galaxy photography is an astrophotography technique to photograph the Milky Way. Here are some basic information about the detailed explanation of galaxy shooting methods:

1. Choose a suitable time and place: It is best to shoot the Milky Way at night without light pollution, away from cities and artificial light sources. Choose a clear and cloudless night to ensure that the moon will not interfere with the shooting. Use the right camera and lens: use a full-frame camera with high sensitivity and low noise, and shoot more stars with a wide-angle lens (such as 14mm to 24mm).

2. Set camera parameters: Set camera parameters in manual mode, including exposure time, aperture and ISO. Generally speaking, the exposure time should be long, the aperture should be large and the ISO should be high. Use a stable tripod: due to the long exposure time, using a stable tripod can avoid jitter when shooting.

3. Use the remote control or delay device: Use the delay device that comes with the remote control or camera to avoid the camera shaking when pressing the shutter button. Take multiple photos and overlay: In order to increase the details of the starry sky and reduce noise, you can take multiple photos with the same exposure time and overlay them with image processing software.

4. Check the photo: enlarge the photo and check whether the photo is out of focus. If so, manually refocus. Check whether the star is obviously trailing. If so, reduce the shutter speed to comply with the 500 rule. Check whether the light and shade of the photo are correct. Please don't judge whether a photo is too bright or too dark by the camera screen, because the screen under the night sky often looks very bright, which will lead you to misjudge that exposure value is just suitable for a photo that is too dark.

Galaxy photography

1. Pre-planning is very important: as long as you have a good grasp of the time of the scene and plan the position and orientation of the composition in advance, as long as the weather is good, there is basically a high chance of shooting the dreamy and dazzling Milky Way.

2. Add foreground when composing: consciously adding some beautiful foreground can make the whole picture deeper and the composition more aesthetic. Remember to combine the three principles of exposure: the aperture should be the largest, the shutter should not be long and the ISO should be as low as possible.

3. Be sure to learn retouching: Even though we have done our homework in front, the Milky Way belongs to low-light photography after all, and with air quality, light pollution and other factors, the photographed works can't show the best state of 100%, so it is very important to learn basic retouching skills at this time. If you want to learn photography well, I recommend that you learn to retouch with Lightroom.
