Let’s start by knowing some Lightroom basics
Opening Screen Before you begin editing, it is essential that you familiarize yourself with Lightroom’s most simple tool bars. That powerful software is aimed at photographers, and it features the intuitive interface you would imagine as well as a vast array of tools to help with working on your images.
Key Features of Lightroom
Non-destructive Editing
The main attraction of Lightroom is its ability for non-destructive editing. What this means is that any changes you are doing to an image will not be saved on the original file. Instead, Lightroom saves your edits as metadata and you can go back until the beginning. For astrophotography, being able to make those fine adjustments can make the difference in your final image.
Organizational Tools
Lightroom is an awesome tool that offers strong organizational features, especially for managing your photos. You’re able to set up collections, add keywords or use flags and/or star rating for your images. This is particularly helpful if you have hundreds or even thousands of astrophotography shots from different nights, which helps quite a lot to find them later for editing or sharing.
Presets
One of the great things about Lightroom is that you can create and use presets (a predetermined set of editing adjustments for your image). On the brighter side, these presets can save you time and keep a consistent style throughout many of your photos. You can make your own presets according to the way you edit or download presets from other photographers. For astrophotographers, such a feature could be especially useful: noise reduction or color enhancements (for example) are sometimes something more than one image can benefit from.
