These photographs were made in photo studio, I used two softboxes, one on each side, main on the left and an additional on the right, about 2/3 of a full stop in difference. I placed a black reflector on each side to stop light from reaching the background. I also had a flash with a snood on the right side (can see highlights on the right side of model’s hair).
1 Shadows: value -100 to darken the background
2 Background: mask to darken the background even more
3 Clarity mask on the hair (clarity +60) to add more texture
4 Levels to set the lightest point
5 Curves to increase contrast
