Many students often ask if there are simple ways to shoot a beautiful galaxy, here are some steps.
The prerequisite for a beautiful galaxy is that it is best to shoot when there is no moon in the sky, 2 hours after sunset and 2 hours before sunrise. Here are some steps.
- Mount the camera on a tripod.
- You can use a shutter release, if not, use the camera’s self-timer (turn it down to 2 seconds).
- Set the focus to “Manual Focus” turn off autofocus, the camera will not be able to focus in the dark environment.
- Set the focusing distance to “infinity”, you can focus on the infinity scene in advance during the day, and then mark the focus point on the lens.
- Set the camera to M-mode
- Set ISO to the highest value, but not exceed ISO6400
- If you have a large aperture fixed focus wide-angle lens it can be used, otherwise, pull the lens to the widest setting.
- Set the shutter to 30 seconds.
- Set the aperture to the maximum aperture, such as f/3.5. Of course, if f/2.8 is better, f/4 is acceptable. Here are some suggested combinations:
f/3.5-30″-ISO 6400 (-0.5 EV) *
f/4.0-30″-ISO 6400 (-1.0 EV) *
f/3.5-30″-ISO 3200 (-1.5 EV) *
f/3.5-30″-ISO 1600 (-2.5 EV) *
* = underexposed, but can be remedied in post-production
- Set the white balance to “Auto” (AWB) or “Daylight”, we can use post-production software such as Photoshop and Lightroom to make the sky more colorful.
- To compose the galaxy or starry sky, it is recommended to add an interesting foreground as a silhouette effect. Illuminating the foreground while shooting can also make photos richer!
- It is very difficult to compose a picture in the dark, try to push the ISO to the highest, then use a shorter shutter for composition. When real shooting, remember to adjust the ISO back to no more than ISO6400.
- Fine-tune your exposure after taking a picture. The more light damage (moon or city lights) the lower the ISO.
- Zoom in on the photo. If stars turn into star tracks, you should use a wider lens or reduce the shutter to 15 seconds, but if the shutter is slow, you need to use a larger aperture or higher ISO to compensate.
Pick up the camera tonight and take a beautiful Galaxy.
