The power of the square format
In portraits it all is about the person and expression shown. Some portraits clearly benefit from the square format, they get more powerful.
By choosing the square format the features of the face get more attention and the character of the person becomes more relevant. This portrait has been made in a house entrance, the background almost is pure black and helps to put even more focus on the man shown.
More portraits can be found in the portraits section of the galleries section on this website.
