There are a few ways of getting your images into Lightroom once you have finished your selection. Here are the three ways:
Option 1 – Use the SHIP button
If you use Lightroom Classic, it couldn't be more simple. Select which images you want to edit, or select all with (Command + a) then click the [SHIP] button. Select will look for Lightroom Classic in your applications folder by default. If it can't be found you'll be asked to select where your Lightroom Classic is saved from a finder window.
Note: make sure you don't have Lightroom's import window already open, or the ship button won't work.
Option 2 – Drag and Drop
Select which images you want to edit and drag them from the filmstrip over to the Lightroom app icon, or directly into the Lightroom window. Again, make sure Lightroom's import window is not already open.
Option 3 – Import in Lightroom
Inside Lightroom, import the folder where the images are saved. This will import all the images so you’ll have to apply a filter to get your selection.
