Yes, that's a much better idea; and I agree about the 'sharp to fuzzy' change; I
wasn't sure how to create that. An area_light is the solution, of course.

Very true. I was lazy. :-(  And there are actually multiple light sources and
positions in the real photo, as you mention. I thought about trying to reproduce
those, but this was just a quick-and-dirty test, to confirm the general idea.

Strangely, I could not find a better personal photo to use, that would clearly
show this shadowing trick. But I'll probably find a dozen better ones tonight
