When you say that something is muted, it means that it is softened or subdued. The Muted Mood by Michael Stuart Daley first raises questions with its title but once you see the photos it becomes clear.
There are a wide array of moods a person experiences but instead of focusing on one, this shoot focuses on the in-between and model Gana did a great job. Stoic and emotionless is very hard to do because more often than not the viewer has to feel something to be captured by a photo. In the case of this series of shots, the muted mood of the shoot redirected all the focus to the clothes which Monique Lewis styled exquisitely and Michael Stuart Daley captured perfectly with the lens of his camera.
