natural window light

Just wanted to share a pic of some sweet sisters and the “how” behind it. I only used natural light, no flashes or lights. This picture was taken indoor, next to a large window. The window was to my right, next to the biggest sister. And it was shot simply in front of a white wall, nothing else. I used a bit of a higher ISO setting. My camera body does a pretty great job of handling higher ISO settings. This is an example of that as the ISO was set at 1600. I just needed a little more light.  :)

ISO – 1600
aperture – F 2.8
shutter speed – 1/125 second
lens – 50mm 1.2L
camera body – canon 5D mark II
