Matías Krimer is a psychologist and photographer. He was born in Montevideo in 1982. After completing his studies, he settled in Buenos Aires. In addition to his private practice, he has worked as a psychologist for 12 years in an interdisciplinary program assisting people experiencing violence in a shantytown in Buenos Aires, which is where the material for this book's composition comes from.

Excerpt from Marcelo Percia's epilogue: "Common Danger (diagnostic imaging) arises from clinical appointments in a public space. Encounters with women (many forced to leave their birthplaces to look for work) who suffer violence, humiliation, abuse. Threatened, terrified, exhausted loneliness, with almost no one to talk to. Before whom does one acknowledge impairment, degradation, mortification? This book sounds an alarm. The announcement of danger implies the hope of believing that there is still time to avoid the irreparable. It calls for care, caution, and anticipation of consequences. It warns that life is at risk."
