I am not a photographer, but my girlfriend is, and she is in the market for a studio. Should studio's contain a window for natural light? She is very adamant that it must, but this limits the choices quite a bit. She is very good with using natural light and prefers her photos to look a certain way which she feels can only be done using natural light. Is it possible to mimic natural light with man made light? If it is possible, please provide a link to your photos. Thanks!
