For this photo I used a 105.0 mm zoom with the lens and it was set to a f/5.8 aperture. This photo was originally dark but I edited the photo in lightroom to bring up the exposure. I also wanted the blue to pop more so I used the temp slider and moved it to be more of a cooler tone that way it really shows the outside light that was illuminating from the window.
The blue hue definitely does give this photo a different feel. Between the lighting, wardrobe and expression, it reads as very somber, and gives us a sense of loneliness or thoughtfulness.
