Perico Dominguez doesn't specialize in maternity photos, but he does take a lot of pictures of his wife. That's her in this photo (here's another image from the same set), and it's a striking and beautiful portrait. The nude form creates such strong lines and curves -- especially with a pregnant model -- and Dominguez has emphasized this to great effect with the strong side lighting. I'd guess that he also has a little fill light to the photographer's right to kee the face from getting too deeply shadowed. It makes a magnificent image. I look forward to the photos of mother and son.
