When it comes to working with your photos, you can import them from your desktop computer or directly from the camera you work with. The great thing about Darktable is that it offers a complete and customizable importation system. For example, it even lets you turn a series of photos into a time lapse, among other options.
Once you've opened your negatives, you can go directly to the darkroom where you'll find several panels with all the available options. On the left side menu, you'll find features to catalog the images, get information about them, open the color picker, or manage the masks. Meanwhile, on the right side of the screen, you'll find all the modules available for working with the image itself. One of the great things about Darktable in comparison with other similar tools is that it gives you a non-destructive way to work with your images. Plus, it also offers a change log that you can use to undo any changes or go back to the original at any time.
Darktable offers tons of useful tools and features, making it an excellent option for working with your photos. In addition to everything mentioned above, the program lets you work with 4K and 5K monitors, supports 3D RGB LUT, and includes all sorts of modules, shortcuts, and modes that will make your life so much easier when it comes to working with your photos.
