Gone for a couple of hours, and coming back to this is almost overwhelming. Thanks you so much to all of you for your generous comments!
I have to say my relationship with this sitter just gets better and better. We're becoming a great team, a partnership I really want to go on. She's a remarkable person, and a great friend too.
This was also my first successful attempt using artificial lighting. One single spun aluminum shop light with a piece of white cloth mounted in front to 'soften the blow'. I'm thinking I'll need a larger setup to make it a true softbox, but a decent start. So this is indeed a single light, just the way I like natural light. Diffused.
