Take a look at the picture below. I would like to use to make a plug for natural light. This was taken in a hotel room in Guatemala during the afternoon sun which was shinning through some white curtains which covered the windows.
This was a pure opportunist shot, taken while my wife was playing with my 4-month old daughter. Granted I got lucky, granted, but I wanted to share as it acts as a means to illustrate to not miss the moment and work with the envionment you are given. Everything came together true, but hey, if I hadn't ignored the urge to take out my flash I would have missed this.
Hope you enjoyed the shot, it brings me joy each time I look at it.
Update: The light was coming in camera left going through some soft white curtains which gave it a great feel.
