This is a portrait photography lighting setup from the Swedish photographer Frida Lenholm.
The photo of Alice Bah Kuhnke was for the cover of a local magazine in Sweden.
Frida: – Since I love backlight very much and had a short time, it was a good solution to us natural light and take the picture of Alice in the window.
The window in the back had the strongest light and was facing the sun. The transparent curtains reduced and softened the spill light around Alice. The window and the curtains also created a frame around Alice that accentuated the composition.
There was also a window from the side with less intense light, that worked as a kicker light that and lit up Alice from the side/front and made the exposure more even.
The photo is slightly overexposed and shot with a Canon 24-70mm /F2.8 lens.
