I used a simple 3 light setup with Laura on this set, 160cm Okta with 1200D Aputure from the front sideways, and 2 Nova 300 Aputure Panels with Softboxes as strip lights from the back.
All lights were equipped with grids, so I keep the spill of light to minimal and no light goes to the black curtains behind the model. The acrylic plates I use on the floor are 1,5m x 2m, so its only 3m away from the curtains we use as black background. Normally you can increase black contrast later in post production on the photo with very little effort, but its always better to try to get to your final result during the shoot with the right light placement etc. 2 black vflats on the sides keep the contrast strong and also remove spill light from light surfaces from bouncing on model and background.
