Tips on how to choose a good picture for a portrait

	Avoid blurry pictures, especially when the face is small. If you submit a blurry picture, you will get a blurry portrait – or more likely a request for a clearer picture.
	Avoid flash photography over a dark background. Subtle facial features get lost, giving way to harsh shadows.
	Ultimately, a good option is one where the face is in focus, the eyes are well defined and the lighting is homogeneous. Natural lighting is generally best.
