I came across Miharu Matsunaga Dots portraits several times. It seems like they have been featured on every bigger photography blog. Young Miharu has background from graphic design and dots appears in her other works as well ( TEN TEN series).
I adore Miharu Dot portraits for the silent poetry and purity that covers something deeply human and intimate.
This is something that a lot of young Japanese photographers have in common and it interesting oposite to "overwhelming" western pictures.
