I recently gave an online presentation focused on optimizing photos in Lightroom Classic as part of “The Happiness Hour” series hosted by Linda Nickell (https://lindanickell.com/schedule).

The full presentation was recorded, and you can view that recording on the “Tim Grey TV” channel on YouTube here:
