You’ve probably heard a million times that the best way to get a gorgeous portrait of your subject while indoors is to use window light. What’s so great about window light?
Well, first off using natural light from your window instead of lamps or overhead lights in your house eliminates the nasty green or yellow color cast that artificial lighting usually brings to a photo.
Subject is standing a few feet from the window facing away from it. His entire face is in the shadow while the background is bright – this positioning will generally result in an underexposed photo with dark eyes.
Now he’s facing directly out the window. This one looks much better – his eyes are bright with nice large catchlights, but his face is evenly lit (called flat lighting), which makes his features harder to distinguish in a photograph.
