In the Tizi Ouzou province of eastern Algeria, there is a woman named Halima Badkof who, despite numerous attempts to take photographs, curiously never appears in any of them. This phenomenon has puzzled not only photographers but also scientists.

Halima is over seventy years old, yet none of her identification documents bear her photo, and she is absent from personal and family pictures. Initially, people speculated that she might dislike having her picture taken, but as she persisted, she was willing to try under various conditions. However, whether indoors or outdoors, under artificial light or sunlight, photographers discovered that her image consistently failed to appear on film, leaving only a blank spot.

This phenomenon caught the attention of local senior photographers, who decided to use the best equipment and film to attempt capturing her image once more. After multiple efforts, they found that in all photos taken with Halima, the images of others were clear, but her spot remained just a dark mark. This mysterious occurrence left photographers baffled, prompting them to invite scientists to investigate the issue. Ultimately, this enigma remains unsolved, becoming an enduring historical mystery.
