@xavier cardell: Thanks for your visit and feedback, Xavier ... this is natural light -- taken in a north-facing entrance with three large doors, allowing afternoon light to filter in. I've had the privilege of working with these three kids [yesterday's post, today's and tomorrow's] in an after-school art program ... they're posing as a character in a "master's" painting -- I'm photographing them and then they paint their version of the master's painting with themselves as the central character of the painting.
