Head Light

I talked with my professor about my photos from the second shoot. I found out that I should use a "hair light" This will help lighten up the top of Jen's head. I wonder if this is something that is only needed on brunettes? This is a great piece of knowledge. I looked up some lights on line and, like most equipment they have a price. Maybe this could be a Christmas gift to myself.

Here is a set up I think would work well for me.
