OF course, if I want this image to be more presentable, an adjustment in the brightness around her knees are desirable.
generally speaking, when I am shooting when there is no reflectors or extra lights available as in this shoot, I will try to use whatever is around the shooting location for use as reflectors, such as light color walls, cars with light color metals, glass windows and others. placing the subject and using shooting angle to take advantage of the reflections off those environmental reflectors will do the trick many times. do not underestimate what is around you, they do not look like much but many times they will be just enough to work the magic. I can't count the many times I have use windows, walls and cars on the street as reflectors.
