I love to shoot in natural light, especially outdoors. Window light works great also. Natural light varies so much and so frequently - soft morning glow, sharp midday glare, hazy sunset, cloudly grey cast, twilight blue - so many varietions, hues, tones, color changes, moods, and settings! And when you add the human subject to these natural light varietions, you get a myriad variety of moods, emotions, and contrasts. I can't think of a more beautiful combination - natural light, the human subject, and a natural setting - for creative artistic photography! It's like painting with light!
