About the image

Lighting was one strobe Profoto B1 with a bounce umbrella. The backdrop was a black seamless paper. In post-processing Photoshop (Beta), I masked using a Camera Raw Filter to separate the background. Then using the Light/Shadows slider brought the background up so the studio ambient light made a gradient from the top left to the bottom right. Using the Color/Temperature slider I increased the temperature +18 and the Saturation +18 to achieve a change in color in the gradient.
