Astrophotography is a fun genre with a wealth of knowledge that you could easily spend years diving into. Many landscape photographers like to incorporate the night sky into their work and just need a practical understanding of how to process it in single exposures. This great video will show you just how to do that.
Coming to you from Aaron King of Photog Adventures, this helpful video will show you how to process a Milky Way landscape image using a combination of Lightroom, Photoshop, and a bit of the Nik Collection (though that isn't crucial). Post-processing these shots is really a two-sided thing: there's the technical facet in working with the light to bring out the appearance of the Milky Way in a manner that accentuates it without becoming gaudy and then there's the artistic side, which mostly involves color-grading the image as you see fit. As you can see in the video, King goes for a blue-toned look, but you'll often see photographers choose more purple or an overall less saturated look depending on the context and their personal taste. Once you understand the basics of how to post-process the Milky Way, the rest is up to you.
