Deadpan/Passport
Deadpan as passport portraits show people in their natural state, typically not showing any sort of emotion. They aren’t posed, are not dressed up for the occasion, and seem completely honest. The color of deadpan photographs is commonly de-saturated. While not completely devoid of color, the colors tend to be muted. Some photographs that are recognized for their deadpan photography such as Rineke Dijkstra and Jitka Hanzlová.

In the end I succeeded in creating what I wanted to do. My model has no expression, shows no emotions and is in its natural state and shows a honest facial expression. I decided to make the image in black and white because even if some photographers choice their deadpan images in color, the color of deadpan is commonly de-saturated.
