I think the answer is a tripod.
Answer:
The principals of design seem to be three things
Explanation:
1. The picture seems to have texture
Look closely and you can see how the skin has texture. How is this made? the texture is made by creating patterns in the colors
2. There is a focus point
This picture's focus point is the mustache and the space between his bushy eyebrows. You can tell because that is what is framing the center (the nose) which has the most detail.
3. The medium
Whatever the medium(s) is /are is another principle of it
Finally
the picture seems to make me feel as though the man has a secret with can contribute to the feeling of it (conceptual design)
Hope this helps! :)
