For this photo, I used 0:1 lighting to get a shadow on one side, I also used a light piece of paper to help fill the
left side of her face to that we could still see facial features.
I liked this photo because of it's "sepia" tone. This was unintentional and was pleased and surprised to get such a warm colour. I used 1:1 lighting with the light on the right side being about meter farther away then the one on the left. The shadow produced on her cheek was purposely done by having her bangs block the light.
This was just one that I took randomly, but I really liked it. The lighting was 2:0 with one facing at a 45 degree angle and one right beside her to get the light to shine behind her head, like I said, this was just taken randomly but it turned out better that some of the ones that I had set up for!
