Black and White Portraits

I was visiting my grandkids early one morning and, as usual, had the camera with me. As we were playing I'd grab some shots now and then and would go back to playing.. Eventually, Gwen got tired and sat down and I noticed the nice light on her coming in from the north window so I quickly grabbed the camera and took this photo knowing I'd convert it to black and white. Nikon D750, Nikon 70-200 f/2.8E @ 200mm f/2.8, 1/250, ISO 4,000. Capture One was used for processing.
