I always say that the idea direction for light should be behind the photographer - it doesn't work 100% of the time, sometimes the best light is side light or backlight but let's say you set down your cup of coffee at the table near the window - and lets put a couple cookies next to them for effect. Here are the results:
|Light shining from behind the photographer|
|Light shining from beside the subject|
|Light behind the subject|
|Shot from above with side light|
|shot at 18mm (18-55mm lens zoomed all the way out)|
|shot at 55mm (zoomed all the way in)|
|of course when you have cookies - you have little fingers trying to grab cookies!!|
This principle applies no matter what type of camera you are using...

P.S. In my Advanced SLR class I'll discuss advanced natural lighting - and how to take one shot is several different styles of lighting... you can register for it now before the price goes up.
