Chiaroscuro is an Italian term which translates as light-dark, and refers to the balance and pattern of light and shade in a painting or drawing, it creates the illusion of light from a specific source shining on the figures and objects in the painting. The word chiaroscuro is Italian for light and shadow. Classic artists such as Leonardo DiVinci and Caravagio have also used this technique. It creates a high high contrast light/dark style used in Renaissance painting and later in cinema.

 Rembrandt lighting is a lighting technique that is used in studio portrait photography. It can be achieved using one light and a reflector, or two lights, and is popular because it is capable of producing images which appear both natural and compelling with a minimum of equipment.

My examples of Chiaroscuro and Rembrandt Lighting:

I also experimented with different white balances as you can tell some photos are warm due to using tungsten light, and others are more cooler toned due to using the white fluorescent light setting and some are in between. The model is centered in the center of the frame and the only light is one just one side to create the shadow effect on his/her face.
