A beautiful way to capture a photo when your using natural light is to do backlit lightning. Backlit lightning means that you place your object in front of the light so it hits the object from behind. With this technique you can achieve a beautiful halo effect around your object. If your planing to take a photo like this with natural light you have to look into where you have the sun in the morning or late afternoon because at this time the sun is low and you will get the light from behind. My best advise is to go out and start play around with this technique until you get the result you want!
