Lightroom Classic is my starting point whenever I am importing, reviewing, finding, exporting or printing any of my images.
I start by importing the photos from my camera in the Library Module. I then review them and mark the ones I like with the Flags.
Once I have chosen an image, I select it and move into the Develop Module to edit it for such things as exposure, colour temperature and crop.
If an image needs more complex editing I open it in Photoshop. When the image is finished and saved in Photoshop, it appears automatically as a new image in Lightroom, where you can edit it further or export it as a .jpeg file to use elsewhere.
The best way to think of Lightroom Classic is that it is a collection of several programs, each with its own module. Each of these programs do very different things. However, I only use the Library, Develop and Print modules myself.
Modules
Lightroom Classic has several menu buttons along the top which control the way it works, each acting as a separate module. These are best thought of as entirely different programs which happen to come together in one package. See Lightroom Classic Menus.
Library where you import, export and organise your photos.
Here is a video I have produced about starting to use Lightroom. Currently it is just a test to try out my video skills, but I will keep working on it and produce more and better training videos.
Creating An Online Portfolio
Lightroom has two ways to create free online portfolios or websites, both by synchronising Collections to the web. This can either be by sharing the Collection as a web page, or by synchronising the Collection to your own free website through Adobe Portfolio.
