There is something so timeless and classic about a black and white newborn portrait. The light and shadow, the peaceful baby, the flawless features. It just makes my heart SING!!!
A good amount of your gallery is presented in black and white and color. Not all images look great in black and white. The thing that makes the black and white more impactful is quality of light (well, that just makes a great portrait PERIOD now just black and white).
