Well, I'm retired, so I already had a bunch of free time. But now all the places I usually go to shoot are shut down (parks, beaches, etc.), and I haven't switched mental gears to find something interesting that is available.
Instead, when the stay-at-home orders started, I decided to work through the list of bookmarked tutorials and courses that I've collected in the past couple of years. That seemed like a worthwhile thing to do -- to learn some new things, you know? -- but it's been a very mixed bag. Video is probably my least favorite way of learning, it turns out, and most people who are making tutorial videos have no clue how to put a video together or when a single page of text could replace 15 minutes of video blathering.
There are some exceptions. Robin Whalley has a useful series of YouTube videos on Affinity Photo (mostly on the desktop version). And I'm just starting a free course titled "
Seeing through Photographs" from The Museum of Modern Art, through coursera.com, that looks promising. I've only done the intro so far, but the course has readings and quizzes for each lesson in addition to instruction and is not just a string of videos of people talking at you like most online courses.
