This is a similar shot as the photo above it except for Emily is standing at a slightly different place on stage and the photo has been cropped.  In both photos the light coming from stage right shines down on Emily from an angle.  The whole picture creates almost one diagonal line.  When the photo is cropped like this, it allows this line to be more easily noticed because there is less distraction from seeing so much of the theater and the right stage.  In this picture the light and Emily really become what you notice right away and then it takes a moment to realize the actual setting she is in.  Also, in this photo I lowered the saturation and brightened the picture a little bit.  It changes the way the light looks a little and I just thought it looked interesting and gave the picture more of a theatrically magical feel.
