I am going to use Lightroom 5 for this tutorial but you can also use older versions on Lightroom.
The very first thing that we need to do is to retouch all the images that you want to export. After that go to the Library Module or you can press G.
Now you need to select the images that you want to export. Press and hold down Ctrl/Cmd and then click on the images that you want to export.
Right click on any of the selected image and go to Export>Export.
Use your desired settings or presets and then click on Export.
Once Lightroom starts exporting, you can track down the status of the process by looking at the progress bar at the top left corner.
And we are done here.
Thank your for reading this tutorial. Hopefully we will meet again in three days.
